I hope you can have a Merry Christmas!!!!!!
How about changing the locks, or just getting the new 'keying' system at the hardware store, ask them or at Home Depot, it is real easy to do and he can no longer 'enter' when you are gone, and when home keep door locked. "NO" is a complete sentence.
Sending good thoughts and prayers for you and yours.
Love and hugs,
