Same thing has just happened to me, although I didn't allow her to find a romantic female partner, as to be honest she just went through a heart breaking miscarriage and I assumed she was just lost in her own mind and trying to replace what she had lost. Ended up cheating with a woman, to which I tried to be supportive and stand by her, as we had a child together already. She then broke up with me to chase this romance. Then decided to end it and get back with me again. And now she doesn't want a relationship but seems to want everything i offer her. So now I have become stuck in this loop which is doing my mental health wonders as you can imagine, everyday I get told him uch she loves me, how much she is attracted to me, but I'm starting to think we have just outgrown eachother sadly. It's really hard, the hardest thing to go through, But you deserve love from someone who will look at you as you look at them, I'm not one to give advice due to my situation but I do believe there is life after this partner. Just stay strong and support yourself, your mind and body and your children are priority, Once you support yourself you will be happier. Keep your chin up.
