I've spoken on the trans widows threads before about my ex partner (thankfully we didn't marry or have children, although came close) but in my ex's case it was definitely AGP, with early memories, since childhood, of feeling excited/ashamed when wearing/caught in his mother's or sister's clothes or shoes. IT worker, watched too much porn, self-absorbed, arrogant etc. (What can I say, we met when I was very young and didn't know better.)
I know I'm well rid, and my life is good now, but it's hard to come to terms with the painful fact that this so-called 'transition' (which isn't real anyway) is happening more and more because of the trans lobby/taboo to provide anything other than social acceptance, even when it causes so much pain to the family - whose concerns get swept away by the self-centredness (of the individual) and often ignored by wider friends / family, too.
I'm very grateful to Tinsel and others who are trying to show the other side of the 'stunning and brave' nonsense. It needs to be discussed and (one day, I hope) more effective treatment given to help these people. But I'm not holding my breath.
