I wouldn't start dating someone who had cheated in their previous relationship. I went to high school with my boyfriend so I knew all about his past relationships and how they ended but if I were to get with someone knew and found that out once we were together, that'd be tough. I'd likely distance myself and work towards ending things as a relationship without full trust is not worth very much to me.
I would ask why it happened and see if i was okay with that answer. I have cheated once before. I wasn't really in love with her from the beginning and a friend of hers said that I was really turning her on and so I was more attracted to that and so I failed.
But I learned my lesson and will not cheat with another girl if I am in a relationship.
just because a person cheats in a previous relationship doesn't mean theu will cheat on you. women and men cheat and I have been cheated on. I have also been accused of being the cheater when I never did. although lf the person has cheated more than once in multiple relationships then it isn't worth it.
My ex was a cheater I found out when I came home from work on my lunch and caught her with her ex in my place. They were getting undressed when I walked in I told them to leave they got violent so I called security who handed them over to the police.
