My FIL treats us and other people like cash cows. He's involved in a stupid investment "arrangement" and has been for some years. When we ( myself and other DIL's ) say that we're worried about him he simply tells us to butt out, we are not family and it's none of our business! On occasion we have noticed a shortage of food in his larder so regularly do a food shop, we take him out for meals and we are constantly subsidising him.
He is so wrapped up in himself but will happily ask to borrow more and more money to fund this ridiculous venture. He thinks a van will appear with a stash of money in it!
AIBU to want to give him a wide berth, but on the other hand I want to shake him and tell home that he has lost thousands of pounds in a fruitless scam. He is turning into a devious old man who will try to tap us up for a couple of grand one day and refuse to talk to us the next.
