Lastly, they entered the forest to lose the Nazgul. Tom also kept those in mind while the hobbits stayed with him, and he knew that they would be there as soon as the hobbits leave the forest, so might as well stay hidden and under that protection for as long as the route permits.

But Bombadil's house was OUTSIDE the Old Forest ?
