I told my wife that I won't be cooking for her anymore and now I have been ignoring her
Why don't you want to cook for her anymore?
I cooked something easy for her before but she hurt my feelings by saying it was burnt
Instead of ignoring her, you should speak with her about how she has made you feel. Otherwise she'll think it is worse than it is and it will hurt her mentally.
She's the one who hurt my feelings and she doesn't deserve to be happy.
You need to tell your wife how her comment's hurt you. You didn't mean to burn the food and she didn't mean to offend you. Please try to salvage your relationship.
