Now that Kristin Cavallari, 24,  and NFL quarterback Jay Cutler, 28, have split, new details are trickling in about what ended their relationship.

“Jay Cutler was beyond controlling and didn’t really like Kristin to go out,” a friend of the couple tells People. “When she did go out, he called all the time and demanded to know exactly where she was going and who she was with.”

Just yesterday, news broke that their engagement was off. Kristin is said to be “absolutely devastated,” although the source claims she was the one who ended the relationship.

Over the weekend, Kristin was spotted at The Beverly lounge in L.A. without her engagement ring. An onlooker said, “She was hanging out at a table with Nicky Hilton and Alessandra Ambrosio. She was telling friends how she called off the engagement.”
