Overwhelmed

I agree with Jade - disappoint your MiL, not yourself - tell her you love her food but you have a wedding dress to fit into! Smile a lot and eat the salad or healthy food that you brought, plus a little taste of her meal. Her son DID choose you, she has to deal with that sooner or later, and you don't want a lifetime of trying to please her at the expense of what is right for you and your family. Choose the restaurant for your meal out and research the menu first. I find that I am ok with eating out as long as I know what I will have and can enter it in MFP before we even leave the house. Good luck, and well done for starting this journey, you can do it!
