Peace, I am sorry to say I heard about my x's wedding in a very similar way. I then had to tell our children. This was after the event tho. They have been m 5years now. I am so sorry for you but "if" it is true, nothing you can do about it. Yes they are sick, very! but your x could have done the decent thing and let you know first. Hard to know who is crueler or sicker! Don't let them know it hurts you. They deserve each other by the sound of it.
