Most Helpful Guy
sorry for what happened.
you can't force him to change his behavior to treat you better. the relationship wasn't successful, both of you should accept what happened.
I know you miss him as a best friend, but you need to give him space to take his own responsibility for his life.
I went through the same experience... I remember that it was a difficult decision, but I decided not to be a wall between my best friend and her life.
now, she's happy with her new life, and I also happy that I did the right thing.
sometimes, some people just aren't meant to be together.
