I do too--but the fact is she isn't taking responsibility for being wrong and apologizing--she's being manipulative, thinking of her own needs and emotions, and continuing to hurt him.
She was 100% in the wrong and unless she acknowledges that and takes steps to try to change, there is no way she is not still toxic.
Plus she was happy to be rid of him--and never cared if he was starving, freezing, or being continually raped. She abandoned him for a "happy married life." She flaunts her ring. She flaunts that she has no money trouble.
So, you've been living well while your son has been a semen toilet for all the men he's had to depend on to survive. Nice, lady. Go and fucking die.

Whatever happened to make Momo's mother the way she is, the fact is she is 100% at fault for not protecting her son, blaming the child, and then selling the child to rapists repeatedly. Instead of recognizing that she was in the wrong and begging for forgiveness, the woman intrudes on her son's life just when he starts to be happy to ask for a ring--not forgiveness, a ring. She makes accusations, and when he reacts with anger (as he should) she lashes out and says things to hurt him.
She's *still* hurting him.
I don't know if her trauma made her narcissistic, or if she has borderline personality disorder, or is a psychopath--but it doesn't matter. No doubt she is so absorbed in her own pain and so concerned about herself she doesn't even think she is wrong to hurt her child just to make herself feel better. The fact that she is in pain in no way makes her less culpable for her actions. She is still actively hurting him. She needs to go.
