So my Dad has always been secretive about many things. He also had a hard growing up, his father died when he was 9. He would always tell my mom and my siblings that his mom had hard time after and lived alone until she died. I have just found out from one of his closest friends the reason why he struggles with so much emotionally is not because the early passing of his father, but because he discovered his mother after she committed suicide when he was 14. Now no one really knows about this, he has only told 2 people in his life, and my mom is not one of them. What do I do? Do I bring it up? It explains everything. I'm very confused.
