A Lying, Cheating Story
People are always finding complicated solutions to a simple problem
I knew this girl once who switched phones about every week and had several different accounts on Facebook, all under relatively the same name. I guess she did this in an attempt to keep her "personal" life personal from her fiancé, who apparently knew her well enough to go through her phone regularly. Seems to me the easy thing to do in that situation would be to either start deleting your damn messages or learn to be faithful.
But, who am I to judge, really? I was sneaking over pretty regular (about twice a week) when he was at work at the time. Giving her a bit of something that the poor bastard apparently wasn't capable of giving her. Looking back, I can't help but feel bad for the guy, but people have needs.
Moral of the story : if you don't keep your lady satisfied, she'll find it with someone else. Seen it happen several times, so I'm atleast fairly certain that it's a pretty common occurrence
