I went over the jealousy issue a long time ago when I was a young married person, and decided that it didn't matter if I were the most beautiful, accomplished woman in the world--if he wanted to cheat, he was going to. Therefore, why worry. Why not just place my trust in him and if that trust got shattered, so be it. I mean, Bill cheated on Hillary. My BIL cheated on my sister. My husband's boss had an office affair. My husband works with smart young women. I had no defense. He's all right and so am I. We are loyal. I complain a lot about him, but I got over my yearning to find a lover. I think it must be that one of the themes of your life has to do with betrayal. I think, for me it would really be pretty simple. I told him if he falls in love with anyone, just tell me for Gosh sake and I'll let him go.
