Never go back.
Too many want to recapture their youth and play the FB game of " just old friends" and end up wrecking families.
Grow the fugg up.
This.
I was friends with an old high school flame on FB. She and I grew up together, in the same neighborhood.
She wanted to get back with me, (marry) after being married for nearly 30 years to a decent guy.
I wouldn't do it. Even though I loved her, and she has to be one of the sexiest, hottest women I've ever seen.
Broke her heart that I wouldn't let her wreck her marriage and drive a wedge in her family. She just didn't understand that.... I did understand it very well. I had broken up a marriage in my younger years and lived through the problems that ensued.
I stuck to my guns. She may not be happy with me, but at least she's still with her long time husband, and her kids don't hate her.
