What would you do?

Okay, so the other day I was talking to a very close friend about life in general, and most specifically about the fact that my wife isn't accepting that I'm trans. Her advice was basically to leave my wife, for the good of my mental state. Along with the idea that I should take a solo vacation to S.F. to visit her, and to find myself in the Queer Mecca. God knows there is nothing in this world I want more than to be able to begin my transition, and finally some closer to the man I was always meant to be, but leave my wife...I dunno about that. I'll admit, she has a valid point, that if I don't start doing for myself, I'll never be happy. But it's not like flipping a light switch. I can't just up and walk out like that. AAAAAAAAARRRRRRRRRRRRRGGGGGGGGGGGGHHHHHHHHHHHHH!!!!!!!!! And taking a vacation isn't a no-brainer either. We never go anywhere without each other (work not withstanding). I would love to go visit S.F., and see Beck for the first time in years. I'm afraid though. I'm afraid if I went there, I wouldn't want to come back. Gawd. I don't know what to do here! HELP ME!!!!!!!!!!!
