Is this a form of ‘sexual harassment’?

[Wombat]

This guy has no doubt found your weakness. You stated yourself that you are to polite. Fucks like him don't see it as being polite but being weak. The diff-with woman that get abused/raped or whatever really never see it coming. You do. Do something about it now. You do not want this guy in your life Period. You are the only one that can take charge of YOUR life and rid yourself of this fool. Next time he comes up to you, tell him that he makes you uncomfortable and that you do not need anymore friends in your life. That is all you say. If he tries to keep talking to you. Raise your voice and just simply say LEAVE ME THE FUCK ALONE! Then walk away. That should be the end of it. There is no reason for you to be nice to this guy. It is really pretty simple. Expect anyone that you do not know to be violent! When you think this way, you will not ever put yourself in the position that you are in now.

You put yourself in this position--Now get yourself out before it gets really scary. And stop talking to strangers---That is what they are strange, and you do not need them in your life so don't let them in.
