I agree if something as stupid as reuniting with old friends makes a husband or wife stray then its not a super strong relationship to start with.... But we are humans and if we were smart enough to know what was good for us we wouldn't need to make stuff like drugs and drinking while driving illegal, lol... google search "facebook ruined my marriage" and you will be sickened by the stories.. My office managers sister cheated on her husband by meeting an old classmate online, and she showed me some of the stories online {as I am paying her $24 an hour, lol}, sure its not facebook banging your wife, but its making it easy for "joe classmate" to do it...
I meant it in the way like alcohol causes car accidents, the driver caused it, but alcohol was to blame {or the driver was to blame and alcohol caused it?}... ut I do agree Adam, for some one to be unfaithful it may have just been a matter of time, but as the old saying goes, "some people are only as loyal as their options and opportunities" with out the opportunity to do wrong some people will never do wrong, but you put it in front of them and after a while even the most honest catholic priest is going to touch the alter boy...
