Me (21m) and my best friend (22m) are game design students currently in college, We first met online in 2020, then we met in person in 2021, everything was so good the first year, but then in early 2022, we both started seeing some college girls, I started dating a girl and we ended up in a relationship, same goes for him. Since then, things became different, obviously, but recently, he said that he feels that I don't want to be with him anymore, I asked what might be the reason, he said he don't know. Well, there are some things that I don't like about him, but they don't matter much so I don't tell him about them, and there are a few more things which I also don't tell because I think it might ruin the friendship. We are currently planning on making a big game project and he thinks that I will betray or leave during the production of the game. He said he don't want to talk about it too. What can I do here?
