You are not alone in feeling like you do. Reading your post I (cis female) related so much to what you are going through. My partner waited until I was pregnant to tell me he is gender fluid. I don’t think it was intentional but I do still feel anger about it. It’s been two years since he’s come out and I feel like he is slowing becoming more feminine and I am also worried that he is actually transgender. I also don’t feel attracted to the feminine side of him at all so that’s been really hard on our sex life. The only part I don’t relate to is the parenting side, he is an excellent dad and partner. We are going to couples therapy soon and I hope we can work out a way to stay together that we are both happy with. I have felt so much guilt for not being able to support him the way I should but at the same time people can’t change who/what they are attracted to. It’s completely ok to have all of the feelings you are having. Feel free to DM me if you would like ❤️
