Wife material!!!

Do you guys feel sometimes like your not wife material ..In my situation i just feel like i am so used to doing things for myself and now i have to think about my husband to, i dont mind doing things for him at all but sometimes i am just tired and have to cook for him do he's dinner and he's food for work...we both work same hours! He helps me a lot but sometime I feel like I'm not a good wife for feeling annoyed.
