broke up with my boyfriend (i don't want to give up)

My boyfriend and I are LDR and have a lot of communication problems. Yesterday he did not message me all day only until I had said something about it. I didn't feel right the way our conversation ended that night and I wanted to talk about it and reach closure so I called him this morning wanting to talk about it further so that we could be on good terms. But his reaction was horrible. He was quiet, acted irritated and snapped and told me that I was annoying and just say whatever I want, pretty much wanting me to shut up. I've been dealing with communication problems with him for months and as soon as he said that I just told him it was over and hung up. I felt so fed up and disrespected at that moment. He messaged me afterwards, but all he could say was complainints about how he feels and that I just want to run away and that I am his future and without me he has nothing. I don't want it to be over but I don't know what to do anymore. I feel like I am the only one who is trying to keep our relationship alive. I am so in love with him, but this is making me exhausted.
