waiting for him to break up with me

Everything has been weird between me and my boyfriend for the past month now. I said in a previous post that he thought we weren't meant to be but we talked it out and we were fine. On friday night we were drinking and he got very drunk and cried to me about his father passing away a year before and how he felt guilty and that he misses him but somehow it changed to him saying he doesn't want to break my heart but when I asked why he thought he was going to he would just stop answering. The next day we were fine we acted normal and he told me he was embarrassed. Anyway fast forward to today, he just has barely been talking to me and shoots me down every time i ask to do something ignores me for hours at a time. I just know it's coming and i don't know when but my heart physically hurts and i don't even know what to do anymore.
