I had something like that with a guy who I went to school with and who was kind of a bully and general asshole, tho he’s gay not trans. Many years later we ran into each other at a random house party, he was pretty drunk, and gave me a hug and told me he was really sorry. Honestly maybe the most impressive apologies I’ve ever gotten.

Not saying you have to give these people another chance or anything, just sometimes people can be self aware I guess.
