IMO, if you want to remain married, don't move out. Do you have some family or very close friends in the area? See if you can have some folks stay with you while he is gone to keep you company. You are obviously very very upset and if you allow yourself to stew in things alone I would guess that it will make you more and more upset which will likely cause you to do things to furthe damage the relationship.

Find someone who you can lean on for a while.
