Well, I postponed having a real relationship with anybody until my 42nd birthday(yes, flings here and there, but never intended to stick around), due to feeling inadequate as a man and presenting as a guy, even though I did all the guy things, military, college, vocational schooling in macho trades, nothing helped. I ended up having a relationship with a female, who up to now, supports me and my transition. We mostly bond emotionally my girlfriend and I, due to a brutal schedule, grad school/work full time, but still we're together. I believe my girlfriend will stay with me because I'm her rock, she has told me before, and I totally appreciate her for that and she my rock. I just hope our relationship can tolerate my transitioning further in the near future(i.e. 5 years), as I progress on hrt, ffs/bbl/liposuction and eventually srs.
We all hope to be fully embraced by our loved ones, for what we will become, our new gender and see more our heart, loyalty and love we have for our partners, then our outer shell, we feel we must become.
