My Husband wants a divorce! Can i move on?

My Husband told me last week he wants a divorce & its a solid desicion. He wont try counciling or anything. He is blaming me now because i went out with a girlfriend and tried to get my mind off of it for the weekend. Now its my fault it cant be saved. Im so depressed i cant eat or sleep. He thinks we should act married until were seperated. Am i wrong for wanting to move on so i dont have to deal with this pain?
