Me and my boyfriend have been together for around 2 years. Overtime I've noticed some of my boyfriends flaws and I've been having a really hard time accepting them. We are in the same friend group (around 10 people) and he's been feeling kind of excluded from everyone and I had noticed it too. So I went to ask if there's a reason why my bf has been excluded from the group and I find out that he has called a girl in our group a slur word. (Technically he's allowed to say it since he's a part of that minority but it still felt very weird to say it to someone else.)

I naturally told him what I found out and I told him that he should apologise, but he was too stubborn and refused to do so. So that's when I warned him that if he did not apologise I'd stay with the group of friends despite him wanting to stay alone in the library. Apparently that was a big no no and he expected me to stay alone with him. But this is where things got messy since he decided to have a huge meltdown about it. He put the blame all on me and started telling me how he's going to kill himself, how I should kill myself and even slurring at me.

After that we settled things and I forgave him and gave him another chance yet I can't help but not forget all that he said to me. So I ended up blocking him afterwards and wanting to break up with him telling him I can't stay with someone who wants harm on me. He apologised for everything, swore he would never do it again and how he didn't mean those things and that he loved me and etc. But I still can't help but feel wronged. So am I the asshole for blocking my boyfriend and threatening to break up over this?
