Honestly I just need to vent, like I had this guy friend who was a really good guy friend for like 3 years and we used to sleep together ages ago but stopped because we just weren't compatible but we stayed friends and then like recently he's been acting really really werid, I've tried not to delete him in hope that he's still my friend and now I feel dumb for doing that because he's clearly unhinged and I don't deserve how he's treating me.

First he was saying that racism towards Chinese people in the beginning of the pandemic wasn't real?? And I literally was like you can't say that because you don't know as you are white, how would you know if people are racist to my people if my people aren't the ones telling you? But anyway he saw proof of people being racist and he was like oh sorry and I was still taken back by how he behaved because I'd never seen him be such a prick before and then one night he commented on something I posted on fb, I posted like a joke about wanting to kill myself sort of thing (meme) and he commented on it telling me to kill myself and I was like okay then I will like ??

Then I messaged him like are you okay because you've never been so horrible to me? And he ignored me and he deleted the comment and like every other week he comments on my stuff being horrible and mean and saying bad stuff about me randomly that don't even make sense and then he deletes it?

I'm just fucking done with him now like I deleted him but I'm so upset and angry that he's randomly just become a horrible person?? Like I've never done anything to him, I've barely spoken to him before this all happened, he used to talk to me about his problems and tag me in memes all the time and now this??

Just doesn't make sense and I just want to reply in anger and rage but I've worked hard with my therapist to get better and I don't want to ruin that all just for this guy, I'm just gonna forget about it but it's still upsetting 

What can I do to feel better without confronting him
