I will not say my marriage has survived transitioning, but I will say my marriage is surviving my transition...
My wife and I have been together in a relationship for nearly ten years and have just finished our first year of marriage successfully.
Prior to our engagement, I expressed my fear of my previous transgender expressions; she accepted my proposal anyway. 10 years later, when the stress finally hit critical mass after burying two close friends (one of whom was a mere 3 years older than me) I realized I could not bear to take my true self to my grave... I feared dying without ever living... She insisted I seek gender therapy, and between the two of them, I have found my way. Since then, she has helped me find my way and take the first steps into womanhood. Despite her protests that she is not a lesbian, she has unwaveringly supported me and repeated her love for me - regardless of my gender. Each step taken forward is with great trepidation, not for the fear of changing, but rather for pushing her away in the process. She continues to defy expectations and reaffirm her love.
Her only request has been for me to keep some parts I don't want because they make her happy... Marriage is about compromise and if I have to keep them to keep her, the price is worth paying for such a wonderful woman with such a beautiful soul.
So is it possible for a marriage to survive transition? I don't know, but I hope to prove it is possible... After all, "Love is not love Which alters when it alteration finds"
