Best idea .. Stay out of other people's relationships. You'll usually just become the "bad guy". (But I'm not sure if your advice about her ex is a good idea anyway. Ex's are best left in the past .. Much healthier that way)
My friend is ignoring me because she wasn't happy that I think she has to be considerate of her ex's needs aswell as hers. She won't reply to me and I'm giving her the same advice as she gave me before but she won't listen?
Personally? I'd stay outta their drama.
Sounds like the kind of drama script you could sell on TV soap operas.
