I need some clarity...because this makes NO sense to me!?

So, me and my bf live together but he's been handling some business with his carrer and been away for a few weeks. I went out with my girls on friday and got in around 2am. I guess when I was walking to my apartment my phone accidently called him. When I walked in I put my purse down and got in the shower. When i got out and pulled my phone out of my purse I had 4 missed calls from him and a txt msg. The msg said "so now you're not gonna answer your phone...thought it was cute to call me while you were f**king?" So I call right back and he says tells me to bring him his stuff the next day...i tell him no because that wasn't necessary and he says that he will be over to get it the next day then..then hangs up on me and deletes me from bbm. I try to explain that i just got in the house and that i nvr placed a call to him but he's not hearing me. He never came to get his stuff on saturday but last night I got a txt saying that he would be over today to get his stuff and drop off my key. i told him that we need to talk and he says we have nothing to talk about. WTF!?! What is really going on. We've been together going on 7 yrs...what would make him act like this?? And do you folks really think he's coming to get his stuff or just starting a fight to prove a point (whatver that might be) So confused right now! He knows me better than that!
