Quarterbacks need to take charge on the field – but was Jay Cutler too controlling in his relationship with Kristin Cavallari?

A friend of Cavallari, who knew the couple socially, says the Chicago Bears quarterback made things difficult for his former fiancée prior to calling off their engagement.

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

The friend adds: “He made her choose between him and being friends with a lot of her girlfriends. I’m not surprised it didn’t last.”

Cavallari, 24, and Cutler, 28, were first linked last summer. The former Hills star had been planning a wedding for next spring, and is said to be “absolutely devastated” by the end of her relationship.
