I'm curious to know how much others share regarding their finances with their in laws? My MIL and FIL both feel that it's appropriate to ask me EVERYTHING about my finances e.g. how much I earn when I started my new job, how much I got when I was promoted, what every little repair in our house/car is going to cost. They even try to dictate how we pay certain things e.g. cash or credit card. They recently tried to insist that we pay for our car repairs with cash rather than credit card, to the point that they were insisting on handing the money to the garage themselves on our behalf, for us to pay them back later (WTF??!!).
This frustrates the life out of my DH, but he feels uncomfortable telling them to mind their own business, as do I as I don't want to cause any awkwardness.
We're not exactly helping ourselves by not telling them to bugger off and mind their own business, and I know that. It's got to the point that I've pretty much stopped sharing my business with them e.g. I'm starting a new course for my career and it's going to cost a fair amount, I chose not to tell them because they'll ask me about the cost and try to work out my finances for me. I love that they're involved in our lives, and they clearly care for us a lot, but it feels a little overbearing.
I just want to know what the best way to tell them to back off would be?
