So I know this situation is going to cause alarm bells for many. But hear me out.
My partner’s best friend is a woman, a few years older than him. They met through work and dated for 2-3 months before calling it off. Then they became good friends and she calls him every few days and maybe they see each other every 2 weeks or so. They go on trips to other cities together with a mixed group of friends.
The best-friend absolutely loathes me. She refuses to acknowledge my existence and has said she will slap me if she ever meets me again.
This is because we used to know one another. She confided in me one day that she had feelings for him and was going to make a move. She knew that my partner and I were seeing each other casually but she didn’t know it was getting serious. When my partner rejected her advances she messaged me a hate filled rant about how I betrayed her and then she cut all contact with me.
No great loss as I never liked her but was always polite and friendly.
I genuinely do believe that they are not doing stuff behind my back. But I just can’t get my head around that my partner defends her. He gaslights me by saying it’s funny how much I hate her.
He defends her and says she has mental health issues and he feels sorry for her. But he must enjoy her company to keep doing things with her.
