I currently have a short term t whom we happened to see about 30 years ago as well (as a minor). I am happy with her for what I use her for. I don't think she would be of any use to us as a DID t though. She's just not very... clued on. I would feel like I had to explain / teach her everything and I can't be bothered with that.
We also have email contact with our ex long term DID t and will be having a one-off online session with her soon. We would like to still be seeing her, but we live in different cities now.

Can you see a time when you will be happy / content?
