Boyfriend problems

So my boyfriend and I have been dating for a year now and things has just been rough... arguements big or small it's like probably everyday and if we're lucky just for a week max.  I love him to death but I'm so at my breaking point. He admits he just doesn't listen but he's trying🙄 also runs his mouth even if I'm trying to prove my point!  Honestly I feel like anything I say or do doesn't matter anymore because at the end it just end up the same point. I want to be able to fix it because he's a good guy but I think I just destroyed him as a person when my ex tried to contact me in the beginning ... I hate to lose him because he's been there throughout my senior year and I had a miscarriage and it just hard Bc he doesn't understand how much he means and I need help on having to fix this relationship if not just tell me. Here's some of our mad convos ...
