share lottery winnings with baby mama

DianaL
So...how would you feel if you won the lottery and gave a chunck to your husband/boyfriend/partner, then he decides to give a hefty portion to his baby mama? 
A few other considerations:
- baby mama has historically been bad with money (from hubby's mouth) 
- he's been very financially supportive at all times (even doubling requested amount)
- she didn't ask for more, she's not in need (in fact makes more than he), child is very well covered financially 
Thoughts?
Update: his response is that she's a good mother, if she's doing well then their child will as well. But my focus is on his constant rants about her money mismanagement. How can you loose sight of that with a large gift of money. I like someone's comment about opening an account that she can draw from in a managed way.
