Last weekend I revealed to my parents, more than 25 years after it happened. I was worried about how they would react.
They were generally supportive, and my mom said, "It's good that you're getting help." But even if they had tried to ignore it, change the topic or said nothing, I'm pretty sure I would have felt better about getting it out of me.
I hope your BF gets results that brings him some kind of relief, both with his parents and with the review.
