agreed.
Absolutely.
Her initial "cheating" on him with the "Alpha" may very well been something she initially regretted until her current husband (then boyfriend) didn't sniff it out or possibly pretended not to notice. She then saw the "Alpha" as the guy she could fuck and her boyfriend/husband was the stable beta that would always be there like a lost dog. That was spark that lit the fuse. No doubt she fucked a bunch of guys since then and even in the recent past.
The tell sign was when she told her husband about the cheating, said it was "no big deal" and then had the balls to take him to the reunion, seek the "Alpha" out (with husband in tow) and flirt with him in front of said Beta Husband. She rubbed his nose in it and probably fucked the "Alpha" soon after or was fucking the "Alpha" all the while.
The wife practically cuckolded right there at the reunion.
The husband better start getting his financial affairs in order, protect his assets and prepare to cut this slut off. He can redeem himself by out witting her and leaving her in a gutter to rot.
