Thanks for the replies all. I guess I'm using this thread as a way to write my thoughts down.
Last night was bad. Really bad. Wife and I are not well. She got me to discuss it last night and things were tender than ever, she cried, I cried. She kept asking what I wanted and the truth is I don't know what I want. I want her, I want my family, but I also want to explore ways to lessen my dysphoria. I want to dress a bit and play with make up and present as female, even if it's on my own. Maybe it gets to the point where I want to live part or full time as a woman but I don't know if I will ever get to that point.
It seems ridiculois to just toss aside everything I care about just to explore this stuff, but the dysphoria has gotten so bad that this doesn't seem like such a terrible option.
I told her my whole story, and she is obviously not happy about any of this but we left it at, I could crossdress in my alone time. This relationship is standing on a knife-edge and I'm not sure what else to do.
