My ex has a girlfriend and they're pretty serious. She knows about me being trans and seems okay with it.
My ex on the other hand is still unsure.
But!
Yesterday this gf of his came to my house to pick up my kids for the weekend. And she called me Jay!!! Whoa!! I haven't asked anyone to call me that yet, so I was blown away. It was Jay, she, but still. I'll take it!
Then later I got an email from my ex, and he started it with Hey, J. I was impressed.
At work later last night a coworker asked if I minded if she called my by "girl name." I told her I hated my name so I preferred she not. Later she apologized for overstepping bounds, and I said no, it's not that, I just hate my name. But, you know you could just call me Jay (I'm not out at work). Cuz I call my son D, and my daughter L, so why not call me Jay? She said sounds good!
Jay
