If I was an Asshole

I have officially been divorced for 9 months.  Life is going good.  I'm working my ass off trying to get myself to a better place.  Things between my ex wife and I are good.  She gets her child support money each month thanks to the nice people at the Department of Human Services.  Additionally, if she needs anything extra, she'll text or call me.  This is where the asshole part comes in.  Yes, I know in the divorce papers, it says I have to help with expenses related to the kids.  I'm cool with that.  But if I was an asshole about it, I wouldn't give her money every time she asks, especially when the reason is not directly related to my children.
