I had two people cheat on me, that I know of. I didn’t care about who they were sleeping with, I did care that they wanted to lie to me and that they weren’t taking safe sex seriously.

On the flipside, had a couple of times I was in a poly relationship, met someone new, and then had an existing partner flip out as if I was cheating (despite them having other partners).

Jealousy is a weird emotion, and I don’t really understand it.
