The reason, I ask you few simple questions because I have seen many husbands/wives support each other with their health problems because they want the help.
I only want to say that those issues what you thought has nothing do with divorce reason but the people themselves who have the problem is refuse to get the help each other or neglect respect, communication, etc., that's how their marriage work goes suffer. It's really nothing do with overweight or slim but the people themselves.
I start to have thyriod problem soon after gave the birth to my 2nd child in 1996. My hubby is there to support me and my health until I am able to lose many pounds... It's him who build my self-esteem... I lose many pounds until I'm slim and feel good. I'm still take thyriod pill and watch health foods and take care of my health.
