How are you doing GreySky? So sorry you're here, but glad you found SI. Keep posting - you'll get great support here.
Stopped by to commiserate about the f'd up ridiculousness, yet visceral gut punch of our partners choosing to betray with a High School Girl Friend. This type of A is it's own special hell. They were willing to risk the marriage for THAT? To chase after a nostalgic fantasy that has nothing to do with reality? Hello, High School was years ago! They don't have a clue who that old GF/BF became - what kind of person they are NOW. They only remember the person the AP used to be. Hence.....fantasy. To add insult to injury, in my sitch she's a GF he didn't care that much about. She’s not a long lost first love, they weren’t kept apart by cruel fate. Their brief high school liaison ended when she cheated on him and dumped his ass for another guy! Figures, right? I don't think they’d spared each other much thought over the last 43 years. Until she fished him on FaceBook.
IMO, for the record, and to hopefully encourage you, sometimes the typical affair with a HS ex is not about "a HS relationship that never ended" or "the one that got away" or "Tru Luv 4 Ever". Nothing you did or didn't do caused him to cheat and lie! It's not about any shortcomings in you, and IMO it's not about her or how irresistible she is either. Sometimes the appeal of a HS ex (or "just an old HS friend", or brother/sister of a HS friend) is simple - they're someone who remembers the betraying partner when they were young - when they were _______________ fill in the blank (smarter, more athletic, popular, musical, notorious, a player, a leader, a party animal, a thespian, had all their hair
etc. etc. etc.) Shared history also lends an easy, fake familiarity. And, if they physically bonded in HS, the re-kindling of the connection (although a fantasy) can accelerate the A from 0-60 in a surprisingly short time. Not necessarily because those early romantic experiences were The Best, but because they were The First. In my H's case - what better false mirror of his former self could an unhappy geezer gaze into than an old HS GF? Her ego kibble flavor was especially potent because she knew him back when, and they shared some early physical experiences. It was that simple. And a pathetic cliche to boot. Unfortunately, you and I aren't the only BS here whose partners betrayed with a HS ex. It's all too common.
Please take care of yourself, whatever you decide.
