I don't want relationships or romance in my life. Abnormality?

Sounds like there's no one you would consider worth your time, effort, respect, or anything else at the moment - so you'd rather be single. That's logical, not unhealthy. I'm single by choice too, I've not met a guy I respect yet. Maybe when you meet a girl that meets your criteria, someone who interests you as a person and isn't a skank, slut, whore etc you'll consider a relationship with her because she's different to the rest.. but until then why waste your time on women who aren't suitable for you.
