I want someone that won't project their past issues onto me and have at the very least started to seek therapy or are actively working on their issues.
You won't find him.
Himbos exist.
Most people I've met in therapy aren't really working on themselves beyond a temporary measure. Regression tends to be inevitable and most people find the idea of seeing a therapist shameful.
People "actively working on their issues" as a claim tends to be a red flag for me over how they will be "actively working on their issues" forever. I'd rather find someone confident.
