My in-laws do nothing to help us. We have saved enough down payment to buy a house, but they are not happy. Why are they so selfish?

In-laws like this are rare. They ignore you in life. But they don't support you buying a house. Then take a rest. Why don't they support you? They are not selfish. I'm afraid you'll move in if you buy a house. Put them in the old house. No caregiver. So I am very opposed to your buying a house.
