Yea, for me it was like 25 years but, I just want to be me. I think it causes issue to hold parts of yourself back too much. It just comes out in other places and other ways. Marriage issues as far as I can see are about two people growing apart, loosing a real connection. It can be hard. If it gets real bad as it did for me for a few years ago it takes a LOT of work to come back... never have fully. Sharing the cross dressing with my SO for me, was soft of a... I love my SO but, if she doesn't accept me I'm okay with that... I want to be me and enjoy my short life / time on this earth. I hope my SO is still with me in a few years. If not I will still have lived my life how I wanted to.
I'm sorry things aren't working out with your SO. At least you get to live your life how you want to now :-) Be happy, do what you enjoy, be safe, life is short live to it's fullest w/o causing yourself harm which will make it less enjoyable ;-p
:-D
