yeah, but doesn't it feel awesome just typing that out???????
ok, maybe not yet, but you need to think about yourself, not him. If he had *selfish twit* written on his forehead, (which he does if he couldn't please you while being in a relationship with you) then would you still stay with him? At the moment, in most of your posts, it sounds like you want to. Actually, now that I think about it, there must be great things you like about him.
But there's other guys out there besides him. If you talk to him, apogolise, keep trying to hang around him and stuff, he won't see what a big mistake he's made. He'll be thinking he can feel ok about things because you're still friendly, you're still wanting to date him, even tho he was inconsiderate. Perhaps I should say this more clearly. He should be the one changing, not you. He needs to change his priorities and communication skills, and you don't.
So you shouldn't be here asking us *what happens if he doesn't speak to me ever again?* You should get past that, and the question shouldn't even cross your mind.(tho it happened so recently that I guess it won't feel like that just yet).
Hang in there, and look on the bright side! You're free to flirt and get to know other guys, and perhaps date someone else who's more commited. You're not having to stress about things you think you did wrong.(you didn't do anythign wrong, you told him you were unhappy, got angry, made a little mistake, and HE DIDN'T CARE TO MAKE IT UP TO YOU-the selfish prat)
