A longer explanation below, but basically I'm in a relationship where my partner is getting divorced but it hasn't happened yet and she's still living with her ex who's still legally her husband. Over the past months I've developed an intense fantasy of the two of them sexually reconnecting with each other. I like that they both are still living in the same house, and sometimes she gets sexually frustrated when she doesnt get to see me, and I know he's had little to no action since they decided to get divorced so he's probably feels ready to burst by now, especially since he started TRT a few months back. My gf and I have a strong loving and trusting relationship already, and have role-played about her other ex's and her hooking up, but never her husband. I'm nervous to bring it up. I don't see him as a threat to our relationship despite their history, and even being coparents together. They're just not a good match relationship wise and I provide the emotional support that he just can't. I like to envision a future though where they continue to have a sexual relationship in addition to a friendship and being coparents. She's going to think I'm crazy, but this is really what I want, as long as she's into it. I'm afraid to tell her though. How should I go about it, droping hints, and seeing how she feels about it. Should I plant a seed or just straight out tell her?
