I'd let it play out. Don't know if it's good or bad, but I do know that you just need to worry about yourself. Your wife's relationship with her dad and whether she goes to counseling is not within your control. She probably is depressed and probably could use help. If he manages it, good for you. I just wouldn't chime in with your own fixes.
You cannot be lonely if you like the person you're alone with. Dr. Wayne Dyer
