<human>: I need a little advice

My wife and I have been dating for 5 years and recently got married July 2014. She's not feeling so well about her health and diet and wants to change it. I'm totally okay with that. I'll even help her prepare he meals (I tend to cook more often). The thing is...she wants me to jump aboard otherwise she feels she'll relapse into her old eating ways. I tell her, she has to learn self control and do this on her own. She shouldn't need anyone to help her. The desire to get better and want a personal change should be enough of a driving force...especially if it concerns health.

I'm fairly healthy and really enjoy my fatty mexican diet (tastes like home). I don't want to alter my diet. She says I'm selfish in doing so -  but I don't feel that way. I think it'd be selfish to not want to help her improve he health. We've discussed how I would help her, but she won't accept that I won't help her (by joining her diet)...saying even that I don't care about her or her health.

Any thoughts?

Can you provide a brief overview of the text?
<bot>: Wife wants to diet and include me in it. I don't want to. Small fight over it (well at least butt to butt sleeping position)
