My friend from high school is in a long distance relationship for the past 9 months. Lately me and him have been going our separate ways. But his girlfriend has him wrapped around her finger . And even in person when we bring up girls around him and the guys , he would say “I’m retired” and that he can’t look at other girls. We’re only in our early 20s and it’s really strange for someone to retire from the dating game and getting girls at such a young age. And it’s gotten to the point in my friendship where his gf has disrespected me and he acts like it’s my fault. I don’t know what to do. It’s very upsetting. Any tips. Thanks
