I want to be with a women, but my partner is against opening our relationship. /u/Moist_Wave85 Sex

I’ve been with my partner for almost 2 decades. I have always liked women but have never acted on it. We have been really rocky over the last couple of years, which has especially affected our sex life. This has left me feeling very unfulfilled and frustrated. I’ve been exploring reddit a lot and have found so many things I want to explore, and he is so close-minded to everything. I don’t know if there is anything I can do to make him understand that I need more? I’ve asked him for a threesome, I’ve asked him to open the relationship, and we’ve even almost separated, but we always end up back where we started because being together is the most logical decision right now. But emotionally, physically, and sexually, I am not happy. I don’t know what to do.
