I had a T I would write to once a year for 10 years. This year is the first year she didn't respond back That's okay. I can let her go now.

Anyways, I wrote to her about everything. The only thing I did was to not seek support in anyway. She still cared, but I had to remember she's no longer my T.

I'd say write whatever you'd like. Don't just whine and complain about things. Don't ask for anything in return except maybe a reply. But feel free to include how you're doing in your daily life: good or bad. You can even tell him how grateful you are to him. You aren't strangers. Just remember he's not your T anymore either.
