Want to break up

Pretty amazed that you went back after he cheated on you for months.
I'd break up, no doubt.

I feel like I want to end things with a guy I’m seeing but I don’t know what to do.
Firstly, him and I are not Bf + GF, we’ve never explicitly said we are and he’s never asked, but we do everything that bfs and gfs do. We met almost two years ago and have been so close for that whole time.
Everything was going really well, we had our few ups and downs but nothing too major. Then suddenly, he cheated on me. He was cheating on me for a few months and I found out with the girl telling me. I stopped speaking to him but broke no contact like an idiot lol. We started speaking again but as friends, but it turns out he was still speaking to the girl he cheated with and a few other girls. I found this out and was so upset.
Since then, him and the other girl stopped speaking and we’ve been good. However, I can’t get it out of my head the things that he did and how he took me for a fool. He did so many things after that were red flags like:
- After he said he ended things with her, still messaging the girl he cheated with then deleting the messages (I found them on his recently deleted)
- regularly checked her instagram on his secret account
- messaged other girls and flirted with them
- has another girl at the top of his best friends list as of rn
Looking back there were so many obvious clues but I just didn’t expect him to do something to the extent that he did.
Now we’re at a point where I’m constantly overthinking about the stuff mentioned above and others, and just don’t trust him. I’ve tried to rectify this but it keeps creeping back up. For this reason I feel that I should end things with him. I also think that if someone really loved me and valued me this much, I wouldn’t have gotten cheated on and done dirty the way i was.
Should I just end things with him?
What do you guys think?
