Your husbands issue stems directly from this rule. Now he associates sex with you with sex with gf, especially since she is all new and shiney.
Want happiness, end stupid rule. Otherwise see your relationship with dh ruined and/or gf walk away.
Thank you for responding. My only worry (stems maybe from insecurity) that is because they are having sex that he isn't going to want to have sex with me anymore. I guess I worry about being replaced as his sexual partner.
