Need no more explanation than that.
And congratulations on the next stage of your life!
Short and to the point. There is no need to say anything that leaves the discussion open. Things like keep in touch, maybe if the circumstances were different . . ., or I would stay if, all leave the discussion open. No need to do that. Just be respectful and offer to do whatever you can during the 30 days to make the transition go well.
Good luck and congratulations.
