Do you think insane people can be loved?

I consider myself insane. I only like pain in relationships so I push lover candidates away. I create conflict and and trouble/hurt the opposite sex who is showing me too much contentment or love (not sure why I do that). This always leads me to act inconsistently like an emotional roller coaster and I eventually shortly end up being left behind.

I only do this if I really like the person I’m seeing. But it doesn’t lead anywhere because they give up. Is this behavior caused by an instinct thats telling me the relationship won’t go anywhere?

Lastly, if someone truly likes me, would they stick with me and would it work out? Perhaps these men were somewhat infatuated but not really loving who I am with all the makings and details.
