Cant blame facebook. Its no different than a bar or the shopping mall...or event this forum......a place where you can meet and talk to people.
Its like blaming Smith and Wesson for the murder that happened with one of their handguns in the 'hood last night.
If you are a cheater, you will cheat whether on facebook or at a bar or at the mall or at the end of the street or on this forum.
If you are not a cheater, you wont.
I am on facebook and just got in touch with my 8th grade girlfriend....my first "real" girfriend.....I checked with my wife of 13 years yesterday to be sure she was ok with my contacting her and she said "why would I care?" Grownups can have friends of the opposite sex with their being any hanky panky. God gave us human beinghs self-control.....its a pity more of us dont [sue] it.
73Dart, hang in there man...better to find out now and not 10 years down the road, I say. You are better than her and deserve far better.
