[QUOTE=Ceric;137439913) And police... yeah, last resort.

Just in case this does come up you will want to save those emails, also be sure to note the dates of when he came round. That kind of thing. A well documented problem is much more likely to get a solution via the cops if you are driven to that point. Also by the time you get to that point you may not be "well" emotionally. And working on it now when you are calmer helps more. Also a quick chat with the campus police about what your options are may help. Also if things get worse but you are not ready to go to the cops you may want to talk to your landlord about getting him banned from the complex which would allow you the safty of your own home at least (or he gets to spend the night in jail for criminal traspass)
Best of luck.
