Well there was no rape thank the Lord, but yes I know that. His offender is his father so "in love"- I should hope not. There wouldn't be a confrontation- more like just a mentioning if anything just to let him know that I saw weird things too and he's not crazy and he isn't ripping his family apart for no good reason. That's kind of how he feels right now.
I probably won't bring it up at all. Just let it ride and let the universe do the unveiling of the truths that will come in due time. I do already attend AL-ANON meetings and have for a while and I have the book. I'm doing quite well. I just ask questions on here so I can be better for him. :-) Thanks for all of the input.
