I'm glad I'm not alone in this feeling. More power to the S/O because honestly, I don't think I could do it if a female I loved transitioned to a man, the more I think about it, unless he was a VERY feminine male. I'm just trying to comprehend the thoughts of what one may go through, having to think about possibly redefining their own selves and attractions and if they are religious, reconciling their faith with their partner moving towards the same gender.
One thing is for sure, that whoever my partner might be, she will know I'm trans before we get married.
