I have to admit I am struggling with this now. My wife weighed 105 at 5'1 when we got married. She maintained her weight pretty well over the years including after both kids. I got pretty big before our first daughter was born and decided to lose weight and never gain it back. Now, in the last year we have gone in opposite directions. I am in the best shape of my life and she is at her heaviest (around 150). She refuses to buy new clothes to fit her so she wears the same things every day, does not go out with me, will not allow any pictures to be taken, etc. About the only thing that hasn't stopped is sex because I can find enough attraction to have sex with no problems. I would never divorce her strictly because the weight gain but the problem is that the weight gain creates many other issues that I have to deal with like her moodiness, our social life, etc. She told me she will work out when she is ready. Guess I have to accept that for now. Pushing the issue will only create resentment but leaving it alone seems to send the message to her that I have no problems with it.
