Rhonda, your self-analysis is valid, as is where you perceive your place in the world. Your honesty shines through.
Your angle on this is really no different than many (or most?) on the admirer scene. That they are happy to take you to bed but not to meet the parents, their friends, etc. I've read a few pieces over the last year on what seems to be a very minor movement on the part of some men who find the transgendered woman attractive & desirable, to proclaim it proudly and treat her as any other woman (girlfriend/partner/wife), not just in the bedroom.
Kind of sounds like you have little interest in being that woman, and there's really nothing wrong with it. But don't rule out the possibility of falling in love someday when you least expect it. You had to be fluid to get into your categorical box in the first place, a similar fluidity can get you out of there as well. Either way, I hope you find happiness!!!
