[Talk about a rude awakening for Molly Sims! Days after she
fessed up in a mid-November interview to her under-the-radar romance with Aaron
Eckhart, he dumped her for spilling the beans. "Aaron flipped out," says a source, "He's an incredibly
private guy."
Still, the sudden breakup might be a blessing in disguise for Molly, who had been growing disenchanted with Eckhart. "Molly was surprised that he ended it with her - and by phone - but she was starting to realize he's not right for her. He's so closed off from the world," says the source. "She wants someone a bit more chill. Besides, she feels she deserves a guy who isn't afraid to tell the world they're in love!"]
Geez, Aaron - do you want to pull that stick out of your ass? It's not like Molly is anyone to be ashamed of dating. Oh well, it's best to know that a love interest is capable of being so cold-hearted sooner rather than later.

I do not believe that he dumped her coldly, he is actually quite a gentleman and he does indeed enjoy his privacy and anonymity, so even though she did not say much to the media as has been reported, I think it was another reason for him to call it quits, maybe she is just not his type,he is a regular guy and she seems very hollywood and a bit of an air-head.
