Why did Kristin Cavallari and Jay Cutler end their engagement? The couple isn't talking, but their friends sure are -- and like most splits, it's a little ugly.

One side says Cutler was extremely controlling and couldn't handle Kristin's independence.

"Jay Cutler was beyond controlling and didn't really like Kristin to go out," a friend told 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."

"He made her choose between him and being friends with a lot of her girlfriends. I'm not surprised it didn't last."

Cavallari was spotted partying without her engagement ring Saturday night.

Another source laid the blame squarely on Kristin's family.

"Jay comes from a really good, wholesome family, and Kristin is a reality TV star who comes from a broken home," another pal told

"His family also wasn't overly fond of Kristin's dad and they played a part in having Jay re-think taking the leap with Kristin."

Cutler officially confirmed the split on Facebook today.
