AITA if I blocked a guy and told him to never contact me again?

Hi!! Feel like I was just love bombed and guilted into oblivion lol. I’m F21 and the guy I’m referring to is M27. So, this all started roughly a week ago. I met this guy online and we started chatting, he was super nice, flirty, and open book. We made plans to meet and he let me know that he has roommates so we couldn’t go over to his house, but that he would explain when he saw me.

We meet up a few days later, and his phone keeps going off and I noticed that it’s a girl with a heart beside her name. So I ask him if he has a girlfriend and that’s when he proceeds to tell me that those “roommates“ was actually an ex-girlfriend. I was willing to hear it out because he then told me that she had been very toxic and controlling, and that he was broken up and going to be moving out of the place that he was in with her. We went our separate ways.

Then a couple days later I get a message from said ex. She asked me if me and the guy had hung out. I said yes I was of course honest. She then proceeds to tell me that they are still actively dating. He’s doing drugs all this stuff. I lose it on him. I’m done at this point. He then proceeds to instead of going to her and talking about this…comes to my house and proceeds to show me all of the text between him and his family from the last few months as well as the text between him and her from the last year. And tells me she got him into drugs and that now that he’s leaving he wants to quit. He also wanted to show me these things to prove to me that he wasn’t happy in the relationship, just felt the need to keep the peace and act like they were still dating so he could get his shit in one piece and that whether I was here or not, he was going to leave. After he shows me that stuff, he proceeds to go back to the place that he lives at and breaks up with her “officially” according to him. While this is actively happening, I’m immediately done. I don’t want anything else to do with it so I just ignore him and let it be. (I should also say that he tried to take accountability about going behind that girls back whether he thought he was broken up with her or not, still not okay he went behind her back and lied to me about still being in that relationship.)

Then the next day I tell him that I’m done. Right after that, I get another lovely text from the girl claiming that he was doing more crazy stuff with her and blah blah blah. I sent him her messages and told him to go F himself, that no matter who’s right in this situation, I am not sticking around to figure out who it is. Then he proceeds to buy seven different text app numbers to try to convince me that she was lying, begging to come to my house, prove to me, and show me all of the evidence that means she was lying. So I just kept blocking him and now we’re here…. AITA?
