I don't think you need to have 100% perfect mental health to put yourself out there and to go on dates. I don't believe that there is such a thing as 100% perfect mental health. I think mental health is cyclical even when you work really hard on it.

That being said, there should be some baseline minimum standard for mental health before dating. Self-preservation, boundaries, self-esteem. You can get really hurt by some really bad people if you have poor self-esteem, a very negative outlook + self-image, scarcity mindet, and you are dating.

I've known a lot of women who prioritized dating before working on their mental health and not a single one is better off for it now. Having trauma, serious mental health and self-esteem problems, and dating is like being catnip to predators, users, and abusers.
