Thank you - I spoke with him today about it. And yes, he realizes that his grandparents picked him for a reason. Just unfortunately they are not at their top form and can't always understand that right now. He also had a talk with his grandfather today and tried to work some things out with him that would make them both feel more comfortable about it.
I guess they wanted to write some checks out to give some of their money to church or whose it or whatever. He is worried in their state of mind, they will give out too much and they won't have enough to live in their assisted living situation. And also that they write out some huge check he isn't aware about and then it bounces or other things they need like to pay for the monthly assisted living bounces.
So they determined an amount that is reasonable for them to take out without letting hubby know - for their own independence - but if they take out more to check with him first to ensure there is money available.
At least right now things seem a bit better between him and the grandparents.
