Would you date someone who needs a lot of emotional support? Someone who's been hurt and nearly closed themselves up in their shell?
Of course! We wouldn't even necessarily have to be dating for them to get my support, so long as they have a good heart, and are willing to try their best to personally grow. Unfortunately, it seems the majority of "broken" people are completely selfish and just want to bask in the pity. They aren't worth the air they breathe.
I have in the past and I would now looking back on it but it is a little more difficult than it sounds and I'd have a hard time telling someone to go for it.
I've recently come to the conclusion that I could never be in a serious relationship with friend of mine who I do have some strong romantic feelings for. He's too broken, too crazy. It would destroy what we do have: a wonderful, flirtatious, and intellectually stimulating friendship. (Our conversations are brilliant. Fucking brilliant.)
I'm reading a thread on /adv/ about a guy in a relationship with someone who's been abused. She is being a complete bitch and freeloader but the guy feels guilty about breaking up.
It depends. You see, many people with BPD and related disorders were often abused, and their disorder usually is partly rooted in their negative history. So, would I date a BPD or cluster B disordered person? No. They are abusive personalities. No matter how you try, they cannot be fixed.
