For me it also helps greatly to know I am not alone. And neither are you. Like the others have said its all in how h treats you as to how often this will happen. My h doesnt have to do anything really that terrible to send me right into a tissy. I wonder if I really want to spend the rest of my life feeling this way.
Tomorrow is always a new day.
I find things usually are better the next day when I am having this problem. My prayers go out to the both of you that you can find your happiness you so badly want. This sounds very trite, but TIME is the only thing that helps. Also remember that affairs are not based on LOVE at all. Just the illusion of love.
