Severely Depressed ;(
What everyone else said, plus: Think of all the extra closet space you are going to have for new clothes after your surgery.
After the shock of him being gone, you will recover and be much better off. Try to get counseling so you don't go back to that type of person. Look at all the posters that have gone through the same thing and understand that you aren't alone. Good luck to you.
As many know from my story on here that My husband told me he did not love me or was attracted to me because I was too fat. Even though he himself gained a ton of weight himself. It sucks and I know how you feel. When I would try to diet he would go to the grocery store and buy all the foods that I liked that were trigger foods. I am so sorry you are going through this but he's not worth your tears and I know it's hard for you to see that right now. In time you will heal and you will find someone that loves you for YOU and not for what he wants you to be. I believe in what comes around goes around and he will be hurt deeply someday.
Hang in there and stay positive and don't let him pull you down!!!!
