So I haven't had surgery yet, but I do have some relationship advice for you based on my own life experience. My ex and I used to have that same nightly ritual of putting the kids to bed and then filling up bowls of ice cream, candy, or whatever other junk food was on hand and watching TV together before bed. It got to a point where that was the only thing we really did together, and when I would want to make healthier changes (it was always me who would suggest it) he would go along but then always act like I was the" mom" who would or wouldn't give him permission to "cheat" with dessert on any given night. It was such a stressful thing when I already was trying so hard to stop myself from giving in. But the TV and snack routine would always win out in the end. Not saying this was the reason the marriage failed, but I sure wish looking back that we had found other, healthier activities we both enjoyed than just watching TV and eating. Even on weekends it would be like "What do you want to do?" and the answer was always, "I don't know, but we could go out for dinner, I guess." I think if you can come up with ideas now that allow you to spend time together in more fulfilling ways (I mean, when you watch TV, you're really not interacting as much as you think), you'll end up a lot happier as well as more successful in kicking the old habits for good. Go for walks together, explore new places on weekends, or try learning ballroom dance from YouTube videos in your living room at night.
