The dinner shit had me cracking up. Exactly the same at my house. My wife will plan meals like 10 days out. I will go to the fridge and figure it out when its dinner time. SOMETIMES theres a plan the day before if I'm making something special, but middle of the week stuff I can usually freestyle. My wife does it to help me though because she works late 3 nights a week, so I'm the one cooking, and both of my kids are picky. Freestyling usually means I make 3 different meals for the three of us. Overall, if she didn't have a plan for everything, we'd probably lose our minds.
There's a lot of great advice on here. This year we'll have been together for 10 years, married for 5. Neither of us are the perfect partner, but we both have always tried for each other, and I know she'll never give up on me. I feel very lucky to have a good marriage, one I truly see longevity in, because I have friends who are truly miserable in theirs. My wife's got a group of friends, who luckily I get along with all the husbands, but almost all of their marriages are pretty rocky. One couple, probably my two favorite people out of the group, basically hate each other and cannot get along. As much as I love both of them, I wish they'd get divorced so they each could be happy. They're good people, but they dated when they were teens, got pregnant pretty early and then married. I've known them long enough to know that they've both tried, but just from what I see it can't work.
A lot of the other issues I see just come down to jealousy.
