he has answered your question. Adjust your actions
He has no interest in the marriage. Get legal advice sort your finances. Move on If he wants back in then the hard work must come from him. He is the one who has left the marriage. You did not ruin the holiday for the kids....he did. These idiots will try and pass it off onto you, excuse after excuse. Its bullsh1t, do not buy one bit of it.
good luck
