Dumped me - now stalking me?

To make a long story short, this guy basically dumped me and is now "stalking" me.

He will show up at places he knows I go to over and over again, and will hang around me, watch me, be all touchy-feely, etc, even suggest hanging out, but then never does anything about it. Then he will sometimes completely ignore me and be almost rude?

And I am obviously not going to pursue him since he is the one that messed up to begin with.

Can anyone explain his behavior?
