Question about ed relationship.?

If you had a relationship with a man that you had grown close to and he was really great and treated you well but then after an amount of time told you he wanted to make a major change in his life by getting implants and living at least some of the time as a woman (going out to LGBT friendly clubs, being a woman around the house and possibly going shopping), would you stay with him even help him explore this side of him that you didn't know was there. The guy is totally straight and could even pull off the girl look rather well as he has a good looking yet feminine looking face and a fit but not overly muscular body. Would you run away as fast as you could or stay and see how it goes? I live in an area of the bible belt and most have given very negative feedback, but then others in other geographical areas have been more open to it. I feel there is someone out there for everyone but some may be harder to find than others. What are your thoughts?
