Kaley Cuoco and her husband Karl Cook's split was a shock to some in their social circle.

The Flight Attendant star, 35, and Cook, 30, announced on Friday in a joint statement shared exclusively with PEOPLE that they would be going in "opposite directions."

A source tells PEOPLE Saturday the couple seemed great when they last saw them at the beginning of summer and that there was no indication they were going to break up.

"In the beginning of the summer, Kaley seemed very happy with Karl. They were affectionate and seemed great," says the source.

They add, "The split seems very sudden. It's pretty shocking."

In a statement to PEOPLE, the couple — who tied the knot on June 30, 2018 — said, "Despite a deep love and respect for one another, we have realized that our current paths have taken us in opposite directions."

"We have both shared so much of our journey publicly so while we would prefer to keep this aspect of our personal life private, we wanted to be forthcoming in our truth together. There is no anger or animosity, quite the contrary," Cuoco and Cook continued.
