Bf and I might break up. Should I text to get it over with?

My bf and I haven’t been working and we have been hostile to each other on FaceTime (the only way we see each other now since quarantine) he made some weird comments about racism in his city ( he was angry at a person for saying that his city is racist and I was arguing that he doesn’t get to say people’s experiences with racism aren’t valid) and that made me so upset and we argued. Yesterday we didn’t talk at all and I feel like that was the final straw. We always say we’re going to work on our relationship, he says he will work on himself after I complain about the things he does and says that hurts me but yesterday made me realize that he isn’t going to change. I asked if we can FaceTime tonight but I have anxiety the waiting is eating me alive. Now I just want to text him about our relationship first and if it ends in a break up then I guess that’s it. I know it’s a shitty thing to do but at this rate I don’t really care. I tried so hard to please him and his family but if we end up breaking up and it’s over text I really don’t care if it makes me look bad. I care for him but I’m just so tired of empty promises. Should I just wait or text him now?

EDIT:

I waited for the call and broke up with him. I’m a wreck and very sad right now. He is my first love and I’m so worried that I made a mistake. It feels right but I don’t know what to do with myself he was my first boyfriend.
