Input: So a little bit of background here, I've known my friend since 5th grade (currently in 11th) and we've had a on again off again relationship. I've known his ex since I was little, and I hung out with her and her small friendgroup this summer. She's really nice and actually cares about people. So my friend was staying overnight one night and told me that he was going to ask her out that night. I had known about his crush on her for a while as we had talked about it a lot before, and I kept encouraging him to do it because it was obvious they had feelings for each other. So he asked her out and she said yes, and that happened around 2 months ago. Fast forward to 2 weeks ago, where he was in the school play, where he would interact with another girl, and that's how they met. So my friend asked his girlfriend to prom around the same timeframe, and she accepted. So 2 sundays ago, him and this girl (not girlfriend) went to a party and got super drunk. They immediately hit it off and became "really good friends". I was perfectly alright with this, and felt good for him that he had made a really good friend. Well, it turns out that when I was filming a video on saturday, I was told that he had broken up with her very suddenly, and that he had cheated on her (which was incorrect). I immediately tried calling him, didn't get an answer, but he texted me and I asked about what happened and then we left it at that. He didn't want to admit it, but he broke up with her to go date this other girl that he had talked to for a week. I texted his ex to say that I felt sorry for her and what he had done to her, and she said that it was super sudden and she had no idea it was coming. He asked me the next day if I supported his decision, and I said that I thought it was an irrational decision based on getting drunk with this girl that he had not even talked to prior. I was just pretty upset that he would throw away this sweet girl that he had been "so in love with" and had been dating for 3 months for someone he met when he was drunk and had talked to for a week. I have stopped trying to make conversation with him as much (as he never starts any) and he has made no attempt to talk about it with me, even though he told me he would. I haven't called him an asshole or anythinf, but imo, that was incredibly wrong to do, especially since he always told me how much he loved her and how she made him so happy. AITA here? 

(I forgot to add that at the same party, he said "Man, I love [her name] so much" to my other friend. They were still dating at the time).
