You can tell him you don’t want your Christmas spoiled again so you are not having her over for a repeat performance. Although she mustered an apology the relationship hasn’t improved. He may go along with that plan or he may choose his daughter and blow you off for Christmas. It’s a risk you take by drawing that boundary. If he doesn’t try to make peace once and for all with his daughters nasty attitude towards you that gives you clarity about your relationship with him.
