Everyone has given such good advice. I would agree with Greek. Go home. It's your house, this is the time you have to go home. You need to get some things in order. He should not be able to dictate to you when you can come home. If he wants to be with OW, he can go to her place.

Stay strong. Keep going with your career goals and stick with the 180 rules.
