A big rebounder-but not now- why?

[sugarcane05]

My boyfriend of over a year and half broke up with me June 27th. I've been attempting no contact all month but really have only begun success last Friday. He said he wanted to break up because he wanted to be single for a while and that he had not been single for over four years. when we broke up he was crying a lot- and when I asked him why he said it was because he didn't like to see me cry. But I have cried many times and he not cry with me so I don't buy that. All his friends tell me how grouchy and rude he is. And he never goes out with his buddies. He does most things alone. (movies, clubs etc.) His best friend tells me he doesn't think that he's happy at all. I told his friend that I was basically miserable and he told me BF is miserable without me too. If he's so miserable why isn't he coming back? BF is a huge rebounder. With his ex on both of their breaks he went and made out with two random girls. Then when they broke up he immediately came looking and found me. But with me he hasn't done that. He hasn't even had little flings to make him forget. I sort of understand the drinking thing, because I have been getting sloshed the past two Saturdays and it helps because the pain goes away. I know crawling into the vodka bottle doesn't help but it's a temporary solution to being un happy. Now that I am turnging to it, it's making me understand that maybe this really is hurting BF too. What do you guys think about all of this?
