Ok...you can't be there...can you tell him that tomorrow is not convenient for you? IF you want to be there when he is doing that then tell when would be a good time for you!
DU-there is nothing you can do to stop this. IF this is what he wants, it only takes one person wanting out of the marraige to get a divorce. But...I have read several stories where the D has happened and the people end up getting married again down the road. Your H wants a seperation...who knows, after being deployed, he may have a change of heart.
Think before you contact OW...she may not stick around for your H to get back...don't worry about her...she is just a bandaid! At least follow the advice and wait before you do anything! Many, many HUGS!!!
