This man enjoys hurting you.
And every time he gets away with it without any consequences, he’s a little more sure he can do it again.
That’s not just alcoholism...that’s sociopathy.
Tell your cop friend about the car episode...that’s another incident on record.
It’s your property, it’s your car, he works for you...get out until you can get him out, any way you can.
Have you talked to your family?
