In that case, you should get professional counseling.
There's likely some event (or several) in your past that leads you to this type of person.
Getting professional psychiatric help doesn't mean you're autistic or crazy, it just means that something in you is damaged. If you broke your arm you'd see a medical doctor, yes?
If you can identify why you're drawn to that type of person, you'll be much more likely to resist that draw in the future and find someone better.
