I most certainly agree. Had a friend and former boss who’s ex-wife carried on a relationship with a person from her old high school on FB and left him after 16 or so years of marriage.
He never saw it coming.
Former roommate of mine did the same exact thing. Found a former bf on facebook, chatted him up and within a couple years had divorced the husband and married the old bf. I was just like...ummmmmmm what?
Facebook’s al gore rythms make it so easy to connect with people, including those who are looking for old and new flings.
And it’s free.
