They say that love is blind.I think that's true because my best friend is going out with a man who isn't very nice to her. If she says she would like to go to a concert or a party,he says yes, but then at the last minute he says he doesn't want to go. He doesn't call her for days,and his behavior is making her unhappy. I think she should break up with him, but msybe it's none of my business. Should I try to convince her to break up with him?
