I know couples who have argued over facebook and myspace. They get jealous of any attention their partner gets, which by rights is a fair statement if you have been together a while, women love to attention if you join up as a woman (fake profile) and a few decent photos (realistic stuff) apparently they get asked LOADS of insane questions and guys randomly try to pick up on them. Same for guy if you have that look about you I figure.. I hated facebook recently but only casue I split with the EX so I just blocked her and some of her friends, it pisses you off though when they add one of your friends and you see them flirting each other with you in front of you're eyes, seriosuly got my back up one time.
