You are assuming that investments don't bring spending. But that is wrong. If the maid does not get the 25, a company, a bank, a fund, will get it (as savings=investments). This means the 25 will flow in the economy in both cases.
GDP is a first principles thing. It's designed to measure how much money is spent on consumption.
When the maid gets married, money is no longer spent on consuming her services, and that's the end of the story. Everything else is just accounting. In this example, the 25k of spending in the first case is counted one time extra because it passes through the maid on the way to some other saving or spending.
