I'm sorry good sir or madam, I stopped reading here.

In my personal life experience with abusive people, I find it makes me want to be more in favor of unconditional help for others, not less. Though I have experienced the urge to want to help people less, which you seem stuck in, and I was formerly stuck. I think it's a stress response. It creates a lot of anxiety to keep sizing people up for how they're going to screw you, instead of just accepting them and treating them well. (Yes, there is a difference between treating them well and letting them abuse you.)
