I’m not sure how many women agree with this; but, I think most women in these situations (which happen very often) try to not show fear. Showing fear seems to be what the bad guy wants and it starts a chain reaction.
Don’t show fear. Show courage. The courage to confront the stalker and let him know in no uncertain terms that the price of attacking you is his life. If he wants to put his ego up against your Glock, you can see who wins.
