Great advice! I've found when I run into "that guy," I start to treat them like they want to treat me - as a fun distraction but nothing serious: OK, you want to just play? I can play. I can play with other guys too, until I find one who actually wants to be with me.
It's funny how those exact same guys who are so scared of "commitment" can't handle women who are also fine with not-commitment.
