I do not understand...my feelings are incredibly hurt right now

Okay normally I don't talk about my feelings because personally I stink at it but I don't have anyone else to talk to. My boyfriend has been acting incredibly strange (well more than usual) and I don't know what to do! One minute, he's cool and the next minute it's like I'm freaking invisible! I ask him what's wrong and he will say that it's nothing...but the way he acts around me says otherwise.

I think he doesn't want to be with me anymore which is personally heart wrenching but at the same time we've broken up before and he isn't one to wait to do something like that. He's very blunt and will tell me something as soon as he's feeling it.

But I don't know what to do. Last night he accused me of being afraid to talk to him which I am but that's only because I don't like bothering him. I'm afraid of him growing tired of me and leaving me. With other guys I wouldn't care but he's...different from the others...

Is it just me being worrisome? I mean I have tendency to be like that but I don't think it's me.
