I ended a long-standing friendship with someone who was always having dramas in her life.
She was providing supported lodging for a care leaver and got highly emotionally invested (talked of adoption her lodger after a few years when lodger was about 21).
I followed all of the ups and downs of this, there were various court cases to do with related stuff. I listened to it all and was supportive.
A couple of years later - because of her experience with children raised in care and her knowledge and understanding of abuse I confided in her when I was having a difficult time with my MH due to being abused in my family as a child.
She basically said it wasn't all that traumatic (were talking serious sexual abuse) because I lived in a big house whereas care leaver had no status , care leaver had REALLY traumatic time (yes she did but it's not a competition and doesn't make my experiences invalid).
She then proceeded to tell me incest is 'evolutionary' to keep the human race alive and implied I was making a fuss being bothered by my mother's (complicit) part in it all.
Would never let me challenge any of her opinions on the matter or defend myself. Didn't apologise for the 'evolutionary' comment even though I explained how hurtful it was.
I eventually messaged her and said I was happy to leave the friendship there. I'm certain she still thinks I'm the bad guy 🤷♀️
