He is getting bigger and bigger, with a BMI now at least 30. He has always been slightly overweight, but I am becoming very concerned at this point. He has been saying he will lose weight for about 4 years, but in that time he has gained about 18 pounds. He does not seem to be able to motivate himself at all, either with diet or exercise. I have tried to be encouraging, but I recognise that I would absolutely hate this if the boot was on the other foot and he was telling me that I needed to lose weight. I would probably say it was none of his business. However, I suppose deep down I do feel it is my business. He is putting his own health at risk, and not being a healthy role model for our daughters. I do not believe he is happy in himself. It is affecting our sex life because quite frankly I don't fancy him. I know that is really horrible. I try to cook healthy meals, and give him opportunity to go for a run/ cycle/ do some exercise. I have not voiced the extent of my concern to him. I don't know what to do.
