@aligatorman75,
I agree with Pearlylustre: she's just a spoiled child. Yyou need to talk to her and explain that you are not going to be her and her children's slave for the rest of your life. Just imagine how that will be when the baby is born: will it still be you who will cook both for her and the little creature. If you were a passionate chef, then no problem , of course. Talk to her, don't let her be the man of the house
