I wouldn't stay away from my marital home. If he wants to pursue some gal, by all means be my guest. But if I want to come home, I will... He can leave for the week or weekend... Why should you have to stay away from your home? Why is he calling the shots? And no way is it acceptable for him to use your joint cc to pay for ow's plane ticket... and I find it hard to believe he was not involved with this OW longer than 3 weeks...
