Based on his past history, this sounds more like a gift for them both, rather than a gift just for her.
Unless he is going to school as well, that money should not be used for his benefit. That's not how the GI bill is supposed to work. Whoever is in school should be getting the money. If there is a surplus, it should be put in an educational account to pay for her future school needs. Not be used as additional income for your ex.
I think you are doing the right thing. Why should he make money off his daughter, whether he re enlisted more years or not? He would still be getting a paycheck while enlisted, wouldn't he?
Based on all the information you put out there, my thoughts are he is a scammer and a jerk.

I guess there is an entitlement for school and books and then the stipend is to be used for housing, meal plan etc. I think that is correct. I have an appointment with dd at the VA in a few hours, hopefully that will shed some light on it!
