When we got together, my partner and I made it clear that we wanted to have an open relationship. Even before I met him, I realized that what I wanted moving forward, after many many failed monogamous relationships (no cheating involved, well at least on my part), that an open relationship was what suited me more. This is my first open relationship btw.

I love that my partner and I are so open about each other's exploits, but at the same time, I'm really struggling to unlearn my well-established and toxic mindset of "he's mine, no one else can have him", so when he talks about his escapades, I'm pleased and happy for him, and at the same time, it's like a dagger went straight to my chest.

It's a toxic trait that I really want to unlearn. I mean, when I have my exploits, I do it without guilt, but when it's him, I get all possessive? I'm a douchebag for it. It's just that I've been so used to that mindset that it's hard to fully realize to myself that said dynamic doesnt work in my current relationship anymore. Any tips or advices to help me get my head out of it?
