I agree with SAWE, peaches.. I don't want to make you upset, I know your heart is so big and you just want to forgive, forgive, forgive, and I know you are lonely and seeking friendship, but in the process you get so so hurt

I don't think it's about you
choosing a victim mentality, peaches - there's so much blame and negativity in that - "choosing victimhood" - ugh! But I do think that it's hard for you to look honestly at the faults in other people -- you care SO much -- and I think that ends up putting you in that victim role.
Like SAWE said, the two people who care about you the most are telling you this is a bad move. I would listen to them, and steer clear, and protect your sensitive heart.
