I was abandoned at a young age by my biological mother after her divorce because my father cheated. from then communication with became sporadic before she ghosted me completely. while this was happing my father married his affair partner. despite a rocky start overtime she won me over and we bonded epically after i felt abandoned by my bio mother as i was desperate for a maternal figure. she also regularly defended me from and took my side over my father who was abusive in every regard. down the line when she could she adopted me and divorce my father going as far as too offer me her support and to live with her too. at that point as far as i was concern she was my true mother. Now I'm a teenager and my bio mom is back Ill call Eliza . apparently Eliza has serious cancer and wants to reconnect with me and reconcile. i was hesitant about and all but with advice from my mom decided to give a shot if nothing else for closer and we met up. it went well i think l at first with Eliza apologizing and giving her all her reason and what not and it seem like she was acknowledging what she did to me (though she clams she never could have for seen my father becoming that abusive to me) but when the topic went to who i have been living with and who has been taking care of me and told her who it was Eliza got piss. she begin to rant about how all this was my moms fault for sleeping with her husband and cussing her out with derogatory words and accusing me of "choosing" the woman who ruined our lives. I wasn't willing to to sit their a listens to the person who played a major part of my trauma besmirch the one person who has loved me and stood by me. so i ranted back at her how their was no reason to abandoned me regardless of what her relationship with my father was. she I ranted about the trauma Eliza put me through and how my mom was just their to help me when Eliza wouldn't. in the end I told Eliza "I hope you you can die peacefully knowing I won't give a shit " I left while Eliza was crying and yelling at me. later on a lot of people even including my mom has told me that was too harsh on a dying woman and some have even said Eliza is right about my mom. so Am i the asshole?
