Hmm. I think it's unfair to tell a jealous partner to own up to their feelings and deal with them if you have, in the past, actually cheated on them. However, people who have been cheated on in ANY past relationship may harbour some real jealousy issues, no matter how responsible and safe their new partners may be. That is some of the emotional baggage they will have to sort out themselves eventually. It can get very tiring to constantly apologize for something others have done in the past.
