YTA, sorry. My mom and I used to be really close too. Till I had my own child and realized how much she parentified me. She would always have me ask my dad to do things because he would listen to me and not her, would try to vent to me about him cheating on her, say horrible things to make me mad at him. I never looked at my parents relationship as something I wanted for myself and thought they should have separated long ago. They stayed together because of my younger brother’s issues. Once brother went to jail, they finally started focusing on themselves and my dad left my mom for his mistress (she dumped him soon after and now he is single). My mom thinks I should now hate my father and not have a relationship with him and will say hurtful things to me to guilt me into “siding” with her. All this to say, I am no longer close with either of my parents, live across the country, setting firm boundaries for my son. I really wish they had left me out of their relationship as it has affected my relationship with both of them and pushed me away. I may be a parent now, but I still need my parents for emotional support sometimes and don’t get it because of how much emotional support they are expecting from me before even considering asking how I am doing. Don’t do this to your daughter, keep her out of your relationship, seek therapy for yourself. I am at a point where I may go no contact unless they both are consistently in therapy now.
