I cannot begin to imagine how badly you must feel, since my H never left the house. At least, not physically. Try not to let the fact that he has left, allow you to despair. There is always hope. Sometimes, these bad things happen, just to show us how true happiness really feels.
You did say you would be having some friends over. Sounds like you have a good support system. Take this time while he is away, to work on you, and finding the person you were before all this happened. Many of us seem to lose ourselves in our M's and family, and don't notice until there is a crisis.
Take care of yourself!
