Have you ever been stalked?

Okay.....so when can it actually be considered stalking?? Have you ever been stalked? I don't think I have ever "seriously" been stalked although I have run into a few incidents where an individual was somewhat obsessed with me...and would not take no for an answer in their attempts to pursue me.... not a fun feeling, albeit flattering at first, its not funny after a while.

What do you do when a person starts exhibiting unusual behaviors all of a sudden? At what point does the red flag go up and you leave? Do you stay and try to figure out what's going on or just shrug it off as some sort of passing phase? I don't know the answers, but I do watch a lot of tv and crime shows....have you ever seen that show SNAPPED! Where a cute little couple from middle of nowhere suburbia are living their lives doing just fine until one partner starts acting up and before you know it BAM they don' SNAPPED and went off and killed the other on some wild obsessive tip....

Maybe I watch too much tv?
