answer:Welcome to Fluther. Have you had past lovers? Do you feel that your fiance has visions of you with them? First, you have to recognize that this is about you, not your fiance. It is a self-esteem issue. You should consider getting counseling. It is not as easy as just turning the thoughts and images off. Meanwhile, every time they start, tell yourself that your fiance chose you, loves you, and wants to be with you. Substitute thoughts of you and your fiance making love in new and creative ways. The most important thing you need to do is not let your corrosive feelings leak out onto your fiance. If you don’t take care of this, you will wind up ruining the relationship.
