I really hope you continue to read everyone’s stories every once in a while.  They may not relate to you right now but they are real and they have been lived through.   My story started out just like yours.  My husband and I were best friends.  I felt sorry for him and couldn’t think to do anything but support him.  He said he would start slow.  I put up boundaries.  They were crossed.  Over and over.   He made me shop for him.    Do things I never thought I would do.  But I supported him.   He started getting happier I started sinking deep into depression.  My future was not what I thought it was going to be.  Everything changed.  I was alone.  He had formed tons of support systems.  I had no one.   Five years later I’m finally climbing out of my pit and realizing my needs and wants.  I’m now blamed that I lied about supporting him because I stayed.  I still support him but this isn’t the marriage I want.  Now it’s all my fault.   Now he says he’s still the same person.  If that’s true then the hell I just went through for all these years was fake.   Please I hope you seriously think about what you need and want.   This isn’t the time to put his needs first.  I hope you read this.   I know you’ll think your situation is going to be different but once he has your support buckle up.....it’s going to be a bumpy ride.

If the OP does come back, it's clear she belongs in the MOM section.  

And MJM, no one can change their sex, whether through surgery or hormones.  A person can feminize or masculinize him- or her-self, but every cell in the body is marked male or female.  You can live either more or less successfully as the opposite sex, but you won't become the opposite sex.  The mismatch between being and feeling is in the mind, not in the biology.
