relationships

I had this ex and we would argue constantly, but I wasn't the one that would start it he was. I was talking to one of my friends (we met through him) and she had said something about hanging out one day and I said sure, but 10 minutes later he calls me and starts yelling at me for not telling him about my plans and I said "I was planning on telling you, but you were ignoring me" I said this in the calmest way possible yet he still yelled at me. I had hung up because I cry whenever someone yells at me and he knew that. then he started spamming my phone. I fell asleep crying and in the morning he texted me and said "I want to break up". This has happened multiple times btw and sometimes I miss the comfort he gave me.
