Is he being ridiculous?

My bf and I have been together for a year and a half. I love him so much and he loves me dearly as well. We have the best times together but there are quite a lot of times when we're on each other's bad side. It starts with a simple disagreement, then for some reason it escalates, then I want him to talk it out after it escalates and he chooses to do everything else but sit there and talk it out with me so the issue is gone and dealt with. I have such a big problem with it and we would just be stressed out for hours and even aya because no one wants to give in. I had told him how to help me fix the issues which is be here for me and support me but all I've been seeing is him just ignoring. We  even broke up, he broke up with me the other day and told me that he gave it though and doesn't think it'll work out because we fight a lot.. He's referring to when we do fight, it escalates. I totally think it's fixable, we just both have to give in, communicate and execute the issue but he won't even try. I love him so much but this made me feel so unloved and just blamed. I don't trust him now, I feel like he's completely a different person for making decisions the way he did. I don't understand how he can throw away our relationship of a ute are and a half because of fights we can accomplish together if we did try. HELP
