Husband has desire to be a woman?

My husband expressed to me in the past that he wanted to be a woman.. after he finally told his family I felt i could leave him.. There was a lot going on we lost 2 homes, my work was crazy and he had a small business but didn't want to look for more work. I knew my husband liked womans clothes, but the fact that he wanted to change to one "then" just made me want to run. Now he is going to therapy and wants to make a contract for him to get a job become stable and try to reconcile, but I am so torn... we do have 1 son as well, but lets say I get back with him because the divorce is coming to a close soon, will it be a mistake or should I accept him and let him be a woman? I am bi-curious and I have really mixed emotions on this.. any advice will help.
