my b.f is keep missing
her ex g.f..and he is always sad
about her ex, how she cheated on him and he is always honest about how he feels to me. He says he can't be with her anymore, but still he says the best thing that ever happened to him was meeting her, He says , that he was in love with this girl. I met my b.f 2 years ago, and after a year of dating we broke up, and he went back to his ex g.f , then they broke up, and now we were trying again..
My question is what should i do?
