I have to keep doing this for HOW long‽‽‽

I try, I really try... but my cooking is sporadic since we both work and have 2 kids and I'm the only one who knows how to cook. The other problem is my wife really doesn't seem to care for almost everything I make, plus the kids are even pickier eaters. I have no desire to cook anything since it's super depressing spending a lot of time on something nobody enjoys having. The funniest part is I could care less what I eat yet I always get the question everyday of "so what's for dinner?". Sorry for the rant. I'm just feeling underappreciated these days.
