I suggested to both that they each need some space, but need also to mutually respect who the other is. To force him to deny who he is within is cruel and unreasonable. To force her to instantly deal with his transgenderism is equally cruel and unreasonable. I don't think many people can say this, and certainly not within this TG community. Yet, perhaps the most important thing any one person can do is to look inward, cleanse oneself, develop the inner person, and project the harmony of self-acceptance to the world.
Any relationship is give and take.
Yet, we dream of it, wish for it, attempt to find it. Your relationship with your partner should be like this. If it is not, then there is mending to do. Begin with yourself. Then reach out to your partner.
