Rob is way too hype! More hype than Parker!

Rob is too hype! He is constantly conflicted about his relationship with Laura, but he only seems to want her when she doesn't want him. And when she is liking him, then he loses interest in her and doesn't put any effort into the relationship. I don't really get him at all. I don't think he should have been conflicted by the relationship in the first place. Even in the beginning of their relationship, Rob says he never really had a wild crush on Laura. They never really had that steam, and he cheated on her when she got too boring for him and he was in his phase of not wanting her. when Rob first met Marie, he starts liking her, but doesn't think she likes him because Rob has the impression that she and T-Bone are dating. But, when Marie invites Rob over to her place after the bar, and she begins giving him hints that she wants to sleep with him, he tries to get out of the situation. It's a redundant thing that keep happening with Rob and women, once they take interest he wants to bail out. I'm not sure why Rob is acting this way, but maybe he has commitment issues. Perhaps he only likes the uncertainty but not the real thing.
