Dear Sarah:

Your solution at this point reads more reasonable than my suggestion. Hopefully he will stop staring at you.. and messaging you, particularly outside of work hours and at night. It remains to be seen how he behaves going forward.

You wrote that you feel intimidated by him- try to not show him that you are fearful of him because some people use such fear to their advantage. If he harasses you in any way, and if there is an HR (Human Relations) department where you work- you may want to talk to someone there. I hope you update me in regard to how he behaves next.
