I am after advice on how to approach this topic without ending in divorce. I love my wife, we have 3 teenage kids, and I am really worried about her health. She is very overweight, our kids have talked to me on several separate occasions to say, can you do something. She has always said, never talk to her about her weight. She eats junk food in secret, then says she is not hungry at dinner time. She does no exercise at all, and when I try to encourage to do something together it never ends well. This is such a sensitive topic, and I realize this is mental issue, and that she needs professional help. I would do anything in the world to help, but I feel I can't even get to the starting line.
