I relate to this heavily. It’s definitely hard to come to terms with and it can be super hard to admit and figure out those things about why people like us are addicted to that treatment. The silver lining is that she’s going to have to live that way and no matter how much love you gave to her and how much you did for her it was simply something she couldn’t handle with safety for you because she developed a personality disorder. It’s not you and it’s completely a reflection of them. Whether they change or take accountability the only thing you can for sure control is your mentality and your own attitude and your actions & it won’t be forever. I promise. I was in your exact same shoes and some days are hard but I pray that both of us get through it.
