Dear Abby: I cant forgive my mom for taking back my abusive father

DEAR ABBY: I am estranged from my father and have been since I was 12.(I’m currently 26.) He was emotionally, psychologically and physically abusive to me, and cutting ties with him has been good for my well-being.My mom recently revealed to me that she has reconnected with him and they are dating again.
This is infuriating, and I have been vocal about my disapproval of their relationship.She is convinced I am making the problem much bigger than it has to be, says it shouldn’t affect me and assures me I won’t have to see him.I can’t tell her what to do, but she can’t tell me how to feel.
Today, over the phone, I told her that I’m feeling resentful.After I said it, she started crying, hung up on me and turned her phone off.
I didn’t mean to hurt her feelings, but I had to speak my truth.I don’t want to lose my relationship with my mom, but I feel so hurt and unseen that I’m not sure how to get past it.It’s hard to have a conversation with her even about the weather without thinking in the back of my mind that she is attracted to someone who hurt me intentionally.I want a magic solution to my problems, which I know doesn’t exist.
I’m at my lowest point and I really need some guidance.Please help me navigate this crisis.

You are now an adult with the ability to protect yourself from anyone who tries to abuse you.You cannot prevent your mother from trying to find happiness, regardless of whether you (or I) think she’s making a mistake.
By the way, there is no guarantee that her reunion will be a lasting one.There’s a price we pay for any decision we make.The price your mother may pay is that she’ll see much less of her offspring.
As for you, it may take some ...
