Dear LostInHarlem,

I would hope you know that this isn't a relationship. ( for you )
I would seek help and advice about getting him out of the house.
This is stalking behavior and has been physical already.
Why do you not call the police?
Everything should be documented!
They can issue a restraining order, get him out of the house, make him stay away from your work, and cut off any form of contact.
With that they will give you a cell phone and with one button you will get an immediate response from them as you are in their system.

Be safe, when a stalker has his/her mind set, everyone you are close to is in danger.
There are lots of resources that can help you get your life back.
Listen to people who have been there, have gotten out smart, calm, and safe.
H
