Several times I have been asked out by a friend's ex-boyfriends or ex- husbands. I have obviously declined. However, I have seen my other friends having a fling with their friends' ex-partners without a problem! For some reason, I just cannot bring myself to attach with someone who I know was once in a relationship with a person known to me, I would feel awkward bringing them in front of my same friend? What are your views in this matter?
