Ok I read somewhere it would reach it’s farthest orbit (29d and half) and stays there then.

This is incorrect. The moon is moving away from the earth and will stop. At some point in the future the tidal forces will balance out and the earth-luna system will be tidally locked. From that point on they will remain locked in orbit neither moving away or towards one another unless some other large gravitational force perturbs them (e.g. an extra solar planet wandering through the solar system and passing by earth-luna).
