The average American adult has been through three major relationship break-ups and spent more than a year and a half of their lives getting over them, new research reveals. According to a new study looking at the ways Americans deal with heartbreak, people give themselves an average of about four days to wallow in sadness immediately after a relationship ends. That’s followed by a process of healing that lasts just over six months for a serious relationship- meaning 18 months of post-break-up pain per lifetime for the average person. The survey of 2,000 people from across the country, conducted by Yelp Eat24, also found that Americans have an average of around two tearful conversations and four instances of crying alone following a split. One in three even have a specific go-to comfort food for when they are upset, with ice cream being far and away the number one choice having been picked by 43 percent of respondents - followed by pizza (30 percent), fried foods (22 percent) and cake (18 percent).
