Yes I agree. That is one (of many) reason I quit having relationships. I have come to the conclusion that there are no "normal" people. We all have baggage and most of us try to use another person to sort all of that out.
I refuse to participate in that, in as much as possible for me.
I do not think my method works for everyone. In fact, many tell me that my method is decidedly unhealthy. I disagree. I think I have made the most logical choice for my life.

But yes, people with BPD do seem to attract others with issues. Often times, we will attract those with anti-social personality disorder, because our vulnerability seems to amuse them. Or we will attract damaged individuals, who somehow mistake our emotional intensity for the nurturing they need. And we, not wanting to be abandoned, will do our best to mold ourselves into what they need us to be. We have a talent or skill for that, as we are unsure of our own identity anyway, so why not be what this other person needs, right?
