Just because dh's (dear husband's) ds (dear son)may ask for more money doesn't mean dh will loan it to him. And a loan means it's going to be paid back, I presume, so I don't see what his dds have to be upset about. But I know family relations can be complicated especially when one adds money into the mix.
Dh is right about one thing, imo - his ds shouldn't talk about this with his sisters. Ds is just stirring the rivalry pot.
As for you, I agree with those who say to keep out of it in general. But where it affects you, of course, you have a right to speak up. For example, you obviously have a say in where you and dh live, no matter whose money is involved. And I wouldn't put up with my dh reprimanding me for calling an ill cousin when he's loaning out so much money to someone else (his ds). Yes, it's his money, but if he's worried about expenses, maybe he should think twice about how much he lets go of, even temporarily (assuming ds really will pay it back). But then again, I wouldn't stand for his complaining about my calling an ill cousin, anyhow. I would point out this call was important TO ME, and that I expect him to RESPECT that.
