Peter was a jerk!
I don't understand why she liked him in the first place. He's inseecure, constantly apologetic, can't seem to do anything by himself. She fed him, gave him pep talks, and then after all that he complained he was the one fed up with how the relationship was going and that he's unhappy. Not to mention, how badly he treated her - calling her names, undermining her, and disrespecting her anal traits.
Bottom line is, Peter didn't deserve Vandy. She was insanely good for him.
