eating same food over and over?

i find that i tend to cook the same food every week, just on different days, nothing new. i do have pinterest and look up new foods to cook, but most of them dont make us full lol. and my husband isnt quite interested in most of them, not only that, id have to have full loads of groceries whenever i go shopping for all those food that requires different ingredients. and lose a lot of money too. idk, its difficult. any ideas for me?
