A few months ago, my friend (23m) met a girl through a video game. He told us about it and started chatting with her. At first, he just mentioned her and things like that. Then he started playing different games with her, but he continued to play with us as well. However, that also started to diminish, to the point where he wouldn't even log on to talk anymore. I was a little sad because I had a lot of fun playing and talking with him, but I understood that he liked the girl and wanted to spend time with her. The thing is, he started playing with her and other friends, but not with me. And a couple of weeks ago, I found out they were planning to play a video game as a group. A game they don't play much, but I do, and it was even my friend who introduced me to it. I've tried to think that maybe it was because I don't have time due to my studies, maybe he didn't invite me, but my past experiences tell me otherwise. I'm kind of used to being left out, but this time it really hurt. When he talks to me, I take the time to talk and chat, but when I text him, I only get a couple of hahas and lols. So, these past few days, I haven't put much energy into his conversations. Another friend told me I was acting like an idiot and that I would do the same if I had a girlfriend, and that's the reason why I don't have more friends, which hurt me a lot because I know I'm not very funny, I don't tend to go out to parties or drink a lot, I dedicate myself to studying, playing video games and being with my family. So, AITAH?
