21 Petty Stories About Extremely Messed-Up Things People's Sisters-In-Law Actually Did
We recently asked the BuzzFeed Community to tell us the worst thing their sister-in-law has done. They had a lot to say, so here are some of the wildest stories:
1."My SIL created a donation campaign for her father, who had recently passed away, to pay for funeral costs and fees. She used the money for trivial things for herself like a new gaming system and fast food. When bills came in for the funeral costs, she admitted to spending the money and said she’d handle it. There are still bills coming from the funeral home about the overdue, completely unpaid invoices. I can’t forgive her for that."
2."My husband and I met through his sister, and she has hated me since we got together. When he and I were 15, I got pregnant and had a stillbirth. I was going to name him Jessie, and three months later (she was 23) she named her son Jessie. I still can barely be around her son and her, and her son is 17 now."
3."My SIL (my husband's sister) had her wedding this year 12 hours away as a destination wedding. We weren't allowed to do anything because 'we could get COVID,' but the virus was very well around when she planned the wedding. I have severe food allergies, and she made fun of me for them. She made me bring my own dessert because she didn't feel like looking for a dessert for me. Bonus points for her buying my boyfriend a pie with nuts in it. I'll go into anaphylactic shock because of nuts."
4."My brother's wife tends to be VERY thoughtless. One Christmas when my son was only 6 months old, a relative jokingly asked when we were having another one. My SIL immediately blurted out in front of the whole family, 'Are we sure she's not pregnant again already? Look at that belly!' That was three years ago, and I still have body image issues and think about that all the time."
5."My SIL called me on my birthday to call me a piece of shit because I cut her off six months prior for going off on a racist rant on my Facebook page. She literally waited until my birthday to try to ruin it. Last year, she also told my husband I was 'openly cheating on him with a woman from Instagram' and posting 'nude photos' of myself. First, I don’t know how you sneak out and cheat with anyone when you’re 1) both working from home together 24/7 and 2) there’s a goddamn pandemic. I called her and ripped her a new one, and she went into hysterics and said she had scheduled her wedding five months after ours 'to make her brother jealous' and that I ruined it by eloping."
6."My SIL (my brother’s wife) is worth a mention. My brother and I are the only family we have. We have never been very close. When they got engaged, they didn’t have an engagement party for about six months. She decided to have it after I moved out of the state. When they got married, they texted me a month prior that she decided to elope (she had been planning a wedding) and if I could make it. She invited a bunch of her family. I had also gone through a really rough breakup with an abusive ex, and she told HER FAMILY that I had cheated on him and that’s why we broke up."
"One year when I didn’t have any money because I had moved and started over, I was saving to buy them nice gifts, but I didn’t have enough for myself to pay for my bills around Christmas. So she complained to her family and my brother about how trashy I was for not sending them anything. He takes her side every time. I just don’t bother interacting with them anymore."
7."My sister-in-law got COVID a week before her wedding and didn’t tell anyone. She got my parents and one side of grandparents (who all have health issues) sick because she wouldn’t move her wedding during a global pandemic."
8."When my twins were born, my son was in the NICU. I hadn’t even gotten to hold my own baby yet. I was in recovery and my husband had sent my SIL pictures. My son was lying under a heat lamp with all sorts of tubes and wiring. She posted the pictures to Facebook before I even got to see them. I didn’t want pictures like that on social media. It’s a very private thing when you have a child in the NICU."
9."My newly divorced ex-SIL borrowed the antique oak bed and new mattress set that was to be my daughter’s when she left her toddler bed. A month later, when she showed us the pics of her new bedroom set, I told her we’d come get my daughter’s bed back. She said, 'Oh! I threw it all away in the dumpster.'"
10."We told my SIL that we were planning to adopt from foster care. She waited until I left the room and told my husband that I'd ruin his life worse than his first wife did. She came to visit a few weeks later and tried to have an intervention to get us to stop adopting. She said I was ruining the family in front of my 4-year-old son. She constantly told us horror stories and flat-out lies to get us to change our minds. My husband started to distance himself from her (which she blamed me for) so when the adoption finally went through years later, he didn't tell her and she found out from my MIL."
"She got mad at us for not sharing our joy with her. She wanted us to visit. I said we'd stay at a hotel close to her since we have four kids now and there wasn't enough room in her house for all of us. My MIL let me know that my SIL wanted our biological son to stay at her place when we go down there. That's it. Just our bio son but not the other kids."
11."My SIL met my youngest for the first time when he was 2 years old. She met him and decided she loved him so much that she wanted him. She called Child Protective Services on my husband and me. Child Services made an emergency call on us that night, complete with a police escort. They found nothing wrong. She called them the next day asking if they apprehended my son so she could get custody of him."
12."My sister-in-law asked me to be her maid of honor when she got married. She also asked to wear my wedding dress. I said 'of course' and was thrilled I meant that much to her. She had the wedding without telling me about it. She wore my dress and when it was returned to me, she had hemmed it with safety pins and there was dirt all over the bottom. I never got an apology but I did get called dramatic."
13."My SIL and I had always had a tense relationship, but I tried to at least keep things polite. Among other things, I always made sure to buy her what I thought were thoughtful birthday and Christmas presents. About five years in, her family moved out of state for work. When I came by to say goodbye, my SIL handed me a box containing every present I’d ever given her, all unused and untouched."
"I haven’t wasted my time or money buying her presents since then. When I see my nephews, however, I’m always sure to have a very noisy or messy toy for them. THEY appreciate my gifts."
14."My former sister-in-law announced MY pregnancy on social media before I got the chance to. She didn't even tag me in the post. I was so heartbroken. I knew this was going to be my only child, so I wanted to be able to make my own announcement."
15."I found I was finally pregnant after trying for a while and surprised my in-laws at Christmastime with a box that had baby mittens in it. During the joy and hugging, my sister-in-law looked at us and said, 'Well I’m pregnant too.' She wasn’t."
"Her husband wasn’t even there when she shocked everyone with her false announcement. It went from happy to awkward to WTF real fast."
16."My sister-in-law told my husband he could do better and to find someone else, while I was pregnant with our kid. Her wedding was the week after she did this. I backed out of the wedding and she called me crying and apologizing to save her ass. Nope. I definitely didn't want to be a part of her wedding party after that."
17."When my husband and I moved back to our hometown to be closer to family, we lived at my father-in-law's house while we were house hunting. My sister-in-law also lived there. One day, she stole multiple items of my clothing from our closet and SOLD THEM to one of those stores that buys gently used clothes and resells them. I only found out because she posted a picture of herself in something of mine on Instagram, which led me to looking in the closet and noticing things missing, then remembering she had just sold some stuff to said place."
"She denied doing it even though SHE POSTED herself in my clothes. She lied and said it belonged to a friend of hers who left it in her room. However, this romper had been purchased in a different city, several years beforehand when she was in middle school and wouldn't have been shopping at this store (nor would her friends have). She also lied about taking my other clothes and selling them even though we found another shirt of mine in her room."
18."My sister-in-law actually gave us the opened and used items from her pantry for Christmas one year. Opened and used boxes of mixes, spices, and old canned goods. Another Christmas, she gave us two boxes of Girl Scout Cookies she had kept in her freezer from the March before."
19."My sister-in-law rescheduled her baby’s christening from February to the day my soon-to-be husband and I would leave for our honeymoon. We had to cancel our wedding due to COVID and since the honeymoon is the only thing that we are able to keep, the vacation meant so much to us. She said it shouldn’t be a big deal if we miss a day of our 'trip.'"
20."My sister-in-law — my brother's wife — told my husband, about a month after we got married, that we needed to consult her before we had any kids. My husband didn’t know her that well at the time and was very confused about the interaction. Five years later, when we did have a baby, she referred to my daughter as 'that child' after she was born. She refused to come see her and wouldn’t let my brother come see her either."
"They lived five minutes from us, and my brother saw my daughter two times the first year of her life. They are now divorced."
