How did you find out? Did he tell you or did you discover this yourself?

You said you would 'help him'. I wonder what that means... Help him stop doing that, do you mean? Or help him feel less embarrassed / ashamed about keeping that secret from you.

Maybe... He doesn't really want to read or understand because he has accepted it as something that he likes to do and something that he does and so... He has just accepted it. Maybe... He feels some relief that he doens't have that as a secret anymore so from his perspective there isn't a great deal more to discuss?

I have no idea...

How do you feel about it?

Does it change how you feel about him?
