Hi Chris,
A wise person once said (don't quite remember who) there are only two certainties in life . . . death and taxes. I have transitioned in the sense that I live 24/7 as a woman both in my private and professional life but have not and will likely not (again only two certainties in life ) seek out HRT or surgery. My wife has travelled this path with me since I first came out to her two years a ago. We have had ups and downs, arguments, bad moments, sad moments and a few WTF moments but she continues to love and support me as she does not see a different person from the one she married. Will we stay together into our old age (close anyway)? I would like to think yes and all indicators are that is what will occur but again . . . only two certainties.
Cheers
Marcelle
