Problem:Is OTHER wrong in the post ? POST : Side note: this is long as hell because I needed to give as much as info as possible. Also, he's now 19 and I'm 17 (I know we're pretty young but yeah)

I and my ex met through a video game during the new year 2017. We started to chat a bit and he soon invited me to his discord chat. I made new friends there (I'm still friends with those friends though) and we were getting along well. A year and a half passed and during that time we were in touch actively. He was dating someone at the moment and I was a bit jealous to be honest, even though we had never met. I knew what he looked like and I knew where he lived, we snapped each other occasionally, and face timed each other a few times. 

We started dating in May 2018. The first month was like I was wearing heart-shaped glasses, but in the back of my mind, I kind of knew it wasn't gonna work. I knew we had it coming at some point and I was correct. He started to seem distant and absent and didn't treat me with such tenderness as he used to. I didn't mind it that much as I thought he's probably busy with school work. And one day I woke up and saw a few new messages. They were from him. He said he's not feeling us anymore and asked if we can just be close friends. I was a bit shocked at first but accepted it quickly. To be honest, I really always knew we weren't gonna work. He told me that he will still be there for me since he knew I was going through a hard time. (I have been having mental health issues since early 2017, but at the time I was doing the worst I had been doing so far). At first, it was okay, I was doing well and I didn't put my mind into it but then he started to tell in discord about a girl he met in college. He told me she was the cutest ever and everything. I encouraged him to talk to her but at the same time, I felt so weird having him talk about a new girl literally like six days after he broke up with me. 

Even if I knew we weren't going to work, I felt like some kind of a worn-out toy that had just been replaced. I knew he develops feelings fast but I was still starting to question our relationship even more. Was it all ever serious for him? It was for me since I rarely like someone who likes me back and he was one of them, and now it seemed like he didn't like me that much after all. I felt pretty betrayed, but I kept going for him since he didn't realize that I was doing badly and I didn't want to ruin his joy. I mean he got new friends in college, apparently, a new girlfriend (after 2 weeks breaking up with me) and I didn't want to ruin take the joy from him by whining. 

However, the next thing I realized is that he didn't talk to me anymore. At all. I tried to talk to him because I felt like he didn't want to be my friend anymore and I felt like we were drifting apart. He never answered my messages so I gave up. Even if I didn't want to lose him, I was tired of trying to keep in touch with someone who didn't talk to me anymore. I was still in the chat but it was exhausting. You see, I was going through the hardest time with my mental health issues (That were the most severe atm) and I was trying to deal with the breakup. I tried to navigate my feelings on something else, I worked out and drew and it did help not gonna lie. 

However, at some point, I couldn't take it anymore. Seeing him talking only and every day about her new girlfriend. Like honestly, all the time. We hadn't shared a word for weeks at this point, and I was about to lose my mind not knowing what to do. While trying to focus on y studies and having this all in my mind, I was having a hard time. Like probably hardest than I can remember. I made the decision to leave him for good. I uninstalled discord, unfollowed him anywhere I could, and made sure I didn't have to see him anymore. I only talk to the friends I made in discord. He didn't seem to care since I didn't hear from him for 5 months.

ALRIGHT now to the real deal. I received a message from him last night. He said he misses me and wants to be friends with me again. I said that even if I have forgiven him, I'm emotionally unable to be in touch with him anymore. I explained that even if he doesn't understand what he did wrong, I know that I don't hold any grudges and he doesn't have to be mad at himself but I cannot be friends with him anymore. It took me long not to think about him every day, 24/7 and now that I have gone through it, I really want to close that chapter of my life for good. 

He called me selfish for not even trying to be friends with him? I tried to explain that after all that I just can't and he said I'm a selfish bitch.

AITA? I personally think no but oh well, you tell me
Solution:
yes
