@55Degrees said in Cheating with an ex: It could indicate your friend is chained to their partner's past. Sometimes people have a problem dealing with a new partner's romantic past and feel insecure about the strength of the relationship. Unless there is evidence that points to the partner cheating with their ex, I think it may be problematic to say a categorical 'yes', as some unfounded suspicion can turn into a self fulfilling prophecy. I agree with what @55Degrees has mentioned.. this could be another perspective. May be you can clarify the situation with more cards
