How do you do it? First of all, you don't do it TODAY. Or necessarily even tomorrow or this week. This is a big blow to you emotionally, and you have to give yourself time to process it. But AFTER this week, yes, you are going to need to go on a "Sandy Project" and work on you, and we can help you.
If your husband DOESN'T talk to you about this, and doesn't INITIATE that talk, then I will stand by what I said about the chickenchit little girl having his mommy do his dirty work for him.
