Over the years my father (df) has helped out dh and I with money for our house deposit etc, paid for caravanning holidays and so on. Probably to the tune of around £20k. Dh and I didn't ask for the money as were both working and not hard up. We were both thankful, df said he wanted to help us for his gc future, hence giving us the money.
Df is now ill and can no longer drive. He asked whether we'd like to buy his car. Dh and I said we were interested and would like to think about it, dm told me as df wanted to get rid of it he wouldn't want much for it. Anyway, df said to me a couple of weeks ago that he'd like £8k for the car. Dh and I were surprised as market value is probably more like £6.5k. I said to dh that I didn't want to haggle as df has been very kind to us in the past, we can afford to pay the extra, especially as df loved his car and it would be rude to an elderly person to haggle (he won't be driving again). Df did say he was happy to take whatever dh and I thought it was worth.
So dh has decided, without speaking to me first, that he's going to buy a different car, that is similar to dfs but cheaper. I feel like dh is being a selfish brat, as he openly admits that if df had asked for less for the car then he would want to buy it. Aibu?
