Today my father needed to move DH's car which was parked in their driveway to get theirs out. DH gave him the keys and told him to move it. In the process of this, ny father managed to scrape the front of the car along the wall, ruining the paintwork and knocking off the number plate in the process. I was clearly very angry with my parents and said that they need to pay to have it fixed. They refused to do this, stating it is his car. Anyway, long story short this escalated into quite a fraught argument which when I tried to involve DH he simply shrugged and said "it's done, we'll just have to fix it." And refused to take my side or get involved at all. I think he is annoyed but simply isn't confrontational. AIBU to be annoyed at my parents and DH's lack of support?
