Actually, now that the D is final, you should have him 100% out of the house. Why is he still there at all? Everything is done. Tell him he can go stay at a hotel if he doesn't want to drive home. And if he says he lives too faraway, tell him to rent an apartment closer. This is an excuse, and yes, prior to the D it might be okay. Now it should be 100% over.
And here's your argument for him: As a divorced, single woman you need to insist that NO MEN can stay at your home unless you are married to them!!! This is poor role modeling for your child and you do not want your child to think it's okay for any guys to stay overnight at the house. There should be no excuses or wavering on this.
There is no arriving, ever. It is all a continual becoming.
