FB- I have zero relations with my abusers from childhood, so I can't give much advice. Hopefully it will be a good holiday for your family and you and your brother can reclaim something you have lost. I know I miss all my bros, who were not my abusers, but remained silent even though they knew- but it is what it is. If you can find the words and courage to bond with your brother again, do so. Will be thinking of you.

Josh, my teenage perp was also my bro-n-law, as I told you before. He was 15yrs older and then divorced the sis when I grad from hs. btw... when I did try to talk to him about the 4 yrs he had me, he pretended not to have a clue. Well, we won't go into me, but you are right.... set your boundaries and stand tall. Your healing is your healing. And all of us are different.
