I am married with my husband for 12 years now. He was always a bit controlling and narcissistic but nothing I couldn't handle... until 2 years ago when he decided to announce that he wanted to have a polygamic relationship and it had to involve me. He is heterosexual and I not only am heterosexual as well but also monogamic. He says he knows I am not bisexual but wants me to be for him. For me this sounds like a lunatic conversation - but he gets very angry with the fact that I can't do that. I have no curiosity and in fact just the thought of it makes me sick. My mental health has been deteriorating a lot because of this. We have a 1 year old daughter (totally unexpected) and since she was born, he seems even more frustrated with the fact that he doesn't have what he wants. I told him several times that we should split because I can't seem to find another solution but he doesn't want it, and whenever I mention it he gets angry and gives me the silent treatment. Now for me I can only see that we have to divorce, but is there anyone here with another solution? I have no friends or family for support so leaving will require a lot of planning and I am scared that could be a bad decision for my daughter. Any thoughts are appreciated.
