You and your daughter eat then you throw the rest of it in the garbage. You do not give him any to take in the basement. If he is going to act like a cheating hermit. F him. Should be your attitude. Rejection is one thing, rejection from a fool is cruel.
Tomorrow, Monday morning, you make an appt. with a lawyer. You will be needing at least child support (and preferably/also support for yourself and the household expenses) and a custody agreement as he is moving out. Make sure you have this intact before he moves out. Make sure you will not be financially strapped because of all of this.
And there are ways to complete. There are ways to make a man cry. Depends how counter-intuitive you want to get.
