Hi there, I think the danger of constantly being around someone who does not treat us well is that we start to get used to it, accept it and then that becomes our life. But - we dont't have to! we can say No. Don't put up with it. Imagine that ! A life where the only people around you have to be decent to you - or else - you show them the door.
I am just starting to realize I went from an abusive xAH to a partner with BPD who treated me the same way. Now I am finally saying No. I am going to try having Nobody as a partner because then at least Nobody can treat me badly. I will do this until I become healthier. You deserve better.
