Broken promise (just like that?!)

Dear Teresa,

I don't know why we turned out this way... it is too hard for me to understand because all I ever think about is loving you and doing all the thing that would make you happy. You promise me that you'll never leave me because you want to spend the rest of your life with me. We always talked about our dreams together, the house I'm going to built for you but now I don't know if it's still gonna happen... I did not cheat on you and I never will do that. Why would you let this happen to me? To us? What did I do to you for you to hurt me like this? Is it because I'm ugly and fat? You always treated me like you're ashamed for loving me.
