If he's a very immature male, there may be no help for him. But you can try to talk to him; buy him a book; register him here and have him read the posts for men only.
If all that fails, ignore him.

And if you have to ask his permission to go to the doctor, well,... I better keep my counsel to myself....
In any event, your "change of life" is more important than your "changing him" at this point. Take care of you, first.
Good luck!
