<human>: Can you condense the text into a few key points?

In my last post here, I outlined what was happening. The leasing office sent a letter out (presumably to each of the households) Saying that we will hear each other from time to time, and that is to be expected in apartment living. I feel like the apartment has focused on the domestic disturbance call to the police, the initial point of contact between me and said guest. In reality, the issue is with him threatening me, and now harassing my fiance. The letter said he will no longer be there... The man in question has taken to parking in the complex across the street during office hours, and then just walking back to the unit next to mine. (He has been a guest for over a month, and should be on the lease, but is not). What can I do?
<bot>: Neighbors guest is not actually moving out, despite being told to do so by the leasing office. Has made threats to me, and was harassing my fiance(female).
