I know this thread is a little old now but I came across it while I was looking for another one.
If you don't mind me asking, how did your dad react when you first came out to him?
The texts remind me a lot of some of the messages my dad has sent me. At first he was pretty violently opposed to me being transgender but lately sometimes he'll ask questions like what causes people to be transgender or how long I've felt like this. He still doesn't seem to like the idea of losing his "daughter" but I think he's at least trying to understand now. I just wondered if you saw any sort of gradual change in your own dad like that because I never know what to expect from my family.
