Me and my partner inherently disagree on a lot of important things like screentime/diet/exercise etc. It causes me so much resentment because he just doesn't care. He'll let them watch tv for hours, eats nothing but junk/takeaways himself and then it affects the kids because if I've cooked a healthy meal and he comes home with a pizza they obviously want the pizza.
I'm not anti screentime but I think an hour/hour and a half after school is enough. I love snuggling up and watching a movie with the kids occasionally etc but instead they get endless reruns of top gear or the Simpsons. I try to persuade the kids to come out and walk the dog with me most evenings because I think it's healthy to get some fresh air and exercise (even if its not far just to the park down the road) but if he's home then they of course want to stay and watch tv or iPad instead. I'm not against takeaways but again think it just be a once a week/month treat and not a daily thing.
I just get shot down in flames everytime I try to bring it up. I know some might say leave him but its not possibly financially and also possibly worse as on his custody days I know it'd be endless mcdonald's, greggs, dominoes etc. I just want to do my best for my kids and feel like his attitude is destroying any of the healthy habits im trying to build.
