I see both points of view in this.

I think nagging him will not work, it will just make him resent you, bigtime. If someone nagged me to go workout or eat better I'd legitimately dislike them for it, even if I was overweight and the person was just looking out for me, I'd feel like it was an attack and it would make me more resistant to the idea of doing it.

Maybe a good idea would be, as someone else suggested, trying to do things together with him. Even if it is small stuff like going for a walk together. Can you make him lunch to bring to work? My husband had health problems and I offered to make him lunch every day, and it takes like 2 minutes and he is doing better and we are also saving money as he is not buying food.

Another idea is maybe suggest that you both go get a physical done together. I did this with my husband as well - he really needed one, he had not had one for like 20 years, and I promised to get one as well if he went, so we both got them. Once you have the results you can lay them out and try to work on a plan to help him.

The end result is that I think it may take effort on your part beyond just saying that you worry about him. My husband could worry about me as much as he wants, it would not make me change my life. And I can worry about my husband and tell him this, but he likely would not change on his own, this is especially the case when depression comes into play.

I do honestly think that a big part of marriage is sacrifice and compromise for both parties, as you have to work to keep things good. Sacrifice in this instance is you having to do more to help him. And in his instance, doing something that he does not want to do.

Does this make sense?

Good luck.
