My partner of 10 years and I recently started to date another woman. The other woman has been good friends with my partner for about 5 years and I've never had any jealousy over the friendship. Once we all became sexually involved I became very threatened by their established friendship and I felt like I was going to be pushed out. Neither one of them did anything to make me believe that I couldn't trust them, but my insecurites got the best of me. After feeling like I was losing control over the situation I decided to call things off with the other women without consulting my primary partner. How do I deal with jealousy and envy that I feel? I now realize I have no good reason to feel this way other than myself being paranoid and expecting the worse rather than the best. My primary partner is now trying to decide if she wants to be with me if I cant trust her. I can I overcome these feelings in order to make things work and move foward?
