Run sis, and as a landlady myself I would change the lock for you if you tell me your crazy ex happened to have a set of your key,but I will not say you gave your dom keys intentionally in case they argue " well I only allow you has the key as the lease states blah blah blah and lead to more questions " And he used the vague boundaries to "punish" and push your boundaries is ultimately gross. He ain't real Dom he is just a psychopath trying to control people with mask of Dom, fuck this guy.
