I would say more guys do it cassually... but the girls who do it cassually are more devestating about it (never seen a guy chain women then brag about it like some girls often do) and I think women are often more vindictive than men in an otherwise amicable break up.
Men are generally either ready to let it go, or arn't. Women almost ALWAYS go through a spiteful phase.
