Oh Virgo, I know that sick feeling too well. And at a time of sorrow must make it ever so much worse.
It took far too many lessons before I finally had to stop my son from coming anywhere near my home. Please change your locks and get an alarm (they have ways of getting in through windows or just breaking the lock).
You did the right thing to charge him. Now just take very good care of yourself.
My heartfelt condolences on the loss of your mother.
