My now ex and I broke up about a week ago because it was an on and off relationship for about a year, we finally called it off. We work together and used to get along great before getting into a relationship, there was this girl who I never really like from the beginning that he looked interested and tried to talk to but he never really did anything because it might upset me since we were together and despite the fact I asked him on a couple of occasions if "he liked her"!? He said NO I don't like her and we left it at that.
