Completely, utterly exhausted

Lately I've really been struggling. I come from an extremely toxic, manipulative, controlling and abusive home. I have been away for a few years now after a very horrific abuse incident and me and my SO of 5 years cut off almost all contact. We got pregnant with our baby girl and my parents became infatuated with getting in our lives again. They continued to be as toxic as ever and caused so much stress on us throughout my pregnancy, even got physical with me while i was pregnant. We then, after several warnings, decided to go limited contact again. They seemed to not care whatsoever and made 0 attempts at fixing anything, apologizing, or even trying to contact us. Then when my daughter was born they were back on it. My family told us to give them another chance and i felt really guilty and this small piece of me hoped that maybe my parents might love my daughter differently than they loved me. Well i was very wrong. They put my daughters health at risk at only a few days old, continued their manipulative and toxic behaviors and even started referring to themselves as my babies mom and dad. I knew and had this gut feeling it was very wrong. I tried talking to them about the issues we needed to fix in our relationship before trusting they could have a healthy one with my daughter... they completely blew me off and were solely focused on trying to force me to give them what they wanted (time alone) with my daughter. I dont trust it and i know i never will and it very much so hurts me that i know they dont see their behaviors as toxic or even care to fix our relationship. They use my family against me to try to get me to give into them and i have tried so many times to give them a chance and every time, i get screwed and i have to come to terms all over again that things will never change and it always hurts more and more realizing my parents are not really parents. Looking at my daughter i cannot imagine doing the things they have done or treating her the way they have treated me. it breaks my heart. im finally at my wits ends and am absolutely, utterly exhausted. i cannot give any more chances or make any more excuses. it is affecting my relationship and home life and i swore my daughter would never be affected by the things i was. so im finally calling it quits even though the realization that i will never have good, caring, trustworthy parents, hurts like hell. and i dont know why i still care or why i am still so scared to stand my ground and quit letting them in... i feel like something is wrong with me.. i almost feel like i have some kind of Stockholm syndrome from all the abuse that i cant separate my feelings even though they continuously hurt, abuse, manipulate and cause chaos every time. i just want to end this vicious cycle and get them out of my life
