How come only mentally ill women are into me?

Every single girl I’ve dated (and failed talking stages) have had some type of trauma, mental illness, diagnosis, on medication for mental illness, family issues, and anything else along those lines. It isn’t made clear till after we are dating are full on in the talking stage so you can’t really leave because attraction has set in place and I like being around them (I’d also look like an asshole for leading them on if I just dropped them as soon as I find out) I just got no clue why that type of woman is so interested in me, there’s nothing about me that screams therapist. Does looking like a dad have something to do with it? I just want a way to be able to date people who don’t have issues and end up hurting me. And I’m not saying all with some trauma are mentally ill cause I got SAd by an ex but have no mental illness nor any real trauma from it (wasn’t that bad, and honestly don’t know how people go crazy from it)

TLDR: how do I get mentally ill chicks to stop being the only women that like me?
