Me and my boyfriend have been together for 2 yrs and we've been on and off lately but we just had a real big argument because I waited for him in his house the whole day until he got out of work but when he got out of work he didn't come straight home. I called him twice and he didn't pick up and when he finally did come home he told me he had to clear his head so I asked him why he didn't call me to let me know he was okay and he said he figured I was sleeping but he also called me to come open the door for him(so I figured he seen my missed calls). So I asked him why did he call me to open the door if he thought I was sleeping and he had no answer he apologized but I wanted an explanation and he wouldn't give me one so we ended up having an argument and he told me he didn't want to be with me anymore but changed his mind after I pleaded with him not to break up with me for something so stupid and told me that if I did that again he would break up with me for good... after that I tried to hug and kiss him and he told me to leave him alone so I did and then he left me alone in his house and didn't come back... so after 2 hrs I left and went home I don't know what to do I love him and I don't want it to be over but now I don't know where I stand or if were still together... do you think he really meant what he said and do you think he'll call?

I am not sure I have the energy or inclination to fully explain why I think the way I do, but from what I can tell, it's already over.

You noticed he called you, then tried to tell you he thought you'd be asleep... that seems very suspicious and when you questioned him on it, he became evasive and didn't want to talk about it. That tells me he is concealing his true motives from you, which probably means they're not what you want to hear (i.e. he's not interested anymore).

The episode where he got upset with you is probably an expression of some unexpressed resentment he has for you... otherwise why would he snap at you for such an innocent question?

Finally, he did say he didn't want to be with you anymore. If he didn't want to break up, he wouldn't have said it. It seems to me he's been wanting to break it off for a while; your on-again/off-again relationship is indicative of that, and this is just another piece of evidence towards that conclusion.

I think you should brace yourself for the end.
