Spotted: an unhappy looking Kristin Cavallari walking her dog Bardot in West Hollywood, a day after Jay Cutler called off their engagement.
Was Kristen's "career" really what forced the twosome to call it quits?
Hardly.
While the two cite disagreements over living situations as the cause of their demise—he's stationed out of Chicago and she's an L.A. gal through and through—sources close to KCav say Jay had way bigger issues.
"He was beyond controlling and didn't really like Kristin going out," a pal of the reality-TV star spills to E! online. "When she did go out, he called all the time and demanded to know exactly where she was going and who she was with."
How lame! Especially considering Jay knew what he was getting into when he popped the big Q. It's not like Kristin hid her love of partying (hello, there are, like, three seasons of MTV programming to prove it)!
Consider us Team Kristin on this one.
And trust, Kristin's friends definitely aren't sad to see Jay go either.
"He made her choose between him and being friends with a lot of her girlfriends," our source tells us. "Honestly, I'm not surprised it didn't last."
