I am so sorry, anon, that’s a sucky situation to be in! I feel like a lot of us have been in a situation like this at one time or another.

You have a few paths in front of you.

Path one: The hard path, but the best one ideologically.

Communicate with them, and draw the boundary. Say to them explicitly, hey, you are making me uncomfortable. I don’t feel like you’re interested in what I have to say, and I feel like you’re just using me to dump all of your OC lore on. Some of the things you talk about make me uncomfortable, and I’d rather not hear bout them. That’s not a fair and reciprocal relationship.

And then if they throw a tantrum about it, you block them.

Path two: the easier but kinda shitty path.

Just block and ghost them. It’s not worth the emotional investment to try to talk to them and risk a confrontation.

Path three: the weenie path (don’t do this)

Just sit there and keep accepting a one-sided relationship that isn’t working for you and is making you uncomfortable.
