Well, I've been going out with this guy for about a year and half now and we have been through a lot together, and about 3 months ago we broke up and I didn't talk to him for about a week. Then we started to talk over again.. and its been 3 months now and I'm not really sure what's going on between us, I still sleep at his house and we do stuff once and awhile, but when I was going out with him before I used to do stuff with him all the time like everyday, and I find ever since we broke up things are different and I try to talk to him about it but it seems like he doesn't care about anything. He always tells me that he's just waiting for me to leave him and that makes me think that he's just giving up on us, which makes me really sad. What should I do? Because talking seems to not be doing much right now, and I don't want to be waiting around for ever.

Maybe u just need to move on, if he said that he is waiting for u to leave him, then do that. And maybe after u move on... And you are a way from each other, he will come back and everything will be good. And he will reallive how much he wants to be with u!  ;)

Are you committed to the guy? If you are then you need to tell him that. Show him. Is he committed to you? It doesn't sound like you both got over the original bbreak up. Try to decide if you really want him annd then move forward by showing him that you care. If he keeps blabbing about the past then you might have to let go.

This is one of the craziest things people do to each other. They break up and then after a few weeks or months they get a little lonely and start hanging out again. For one, it is just a way to satisfy themselves sexually, for the other, it seems like hope for the relationship to start up again.
Stop it! You guys have broken up, right? Well, then stay away. It sounds like you're putting yourself through hell and he's getting laid while he looks for a new woman.
You don't need to do this to yourself. From what you say, he has no commitment to you or the relationship so get on with you life.
Simple, but not easy.
