While I know it is hard on you to hear you W say these things, I think it is great she is opening up to you. Even though she "says" she doesn't feel safe with you, she continually shares her thoughts and feelings with you. Actions speak louder than words, right?
A close friend of mine had a horrendous childhood, including abuse. I remember having a conversation about her life (it was awhile ago, maybe when we were in our 20's?) and she said she didn't realize how messed up her upbringing was till she was a teenager and started going to friends' houses and seeing their families. It was a rude awakening to see what was "normal".
She still struggles with everything to this day.
I wonder if your wife still struggles with the reality of what happened to her all those years ago with her brother - and instead of dealing with that, she focuses on you.
You are so compassionate and understanding FY - I hope that one day, your W will see how very much you love her
