I feel your pain. You're going to be ok. People on this board are living proof that you can and will be ok. Better than ok. Anna is right, she has come miles from where she was. Read her threads if you haven't already. At a minimum, it will give you some laughs, that is guaranteed!!
You cannot control what your H is going to do. He will do what he will do. Your feelings and emotions are yours. Yours to feel. But don't let them control you. Instead, think about who you want to be and try to be her, even in the wakes of all your H is doing. Right now is about you. Take care of you and your children. You're going to be ok.
