Thanks, everyone.
I know she read my note, as Facebook is kinda cool about showing that little "Seen by SoAndSo at 3.10pm" or whatever. Never has said anything. I'm thinking she rolled her eyes at it. She hasn't replied, said anything on her profile, unfriended me, nothing. It's as if it never happened.
I do like her husband a lot. There's a weird history there. See, about twelve, thirteen years ago she and I...well, we had a virtual affair via AIM. [There's a throwback for yer.] My screen name suggested to her and others that I was male, and, well, who was I to argue with them? I wanted to transition then, but no insurance, no extra money for surgery. Anyway, she and I got on really well, we cybered, then she finally called it off. Not long after I told her the truth about me being FAAB. She lost her ->-bleeped-<- for a while. We didn't talk for a few weeks. She said she told her husband everything. Funny thing is, the dude STILL likes me! I met the man in person before I met her. I talk to him more than I do her. He hasn't said one derogatory thing about me being LGBT. He's actually a bit of an ally.
I've already talked to him before about her. He knows he has no dominion over her, which I agree with. He's advised me before to just let it go. So I will...for now.
