Give more details. If you are sure they were as you say, and you are able to pick them a mile off - why then have you. Do you want to take care of others beyond your own needs, do you undervalue yourself or simply do you need to be loved beyond all measure.
You can find someone who encompasses all of these things, however you have to want to change for yourself. Not them.

I too am like you, the thing is anyone who treats us like that cannot love us and yet, I would simultaneously give up everything for them, if they too could give me what I need.
