I know the answer and it's harsh but I would tell the boys exactly what he told you. They have to know in case he really won't pay. Possibly if THEY go to him and ask him what's up, he won't have the guts to tell them that he has to "keep up his lifestyle". Mine used to pull that on me but would turn to the kids like he never said that. As Wonder pointed out he has to look like the "nice guy" when it matter most.
Nothing like pulling this a month before school starts.
What a tool!
You deserve sooooooooooooooooooooooooo much better!
