u/theultimatecad posted earlier that she cheats because she is bored. The Cad is right, but that's not the only reason. I've watched up close while one of my wife's friends cheated right and left to try to find an upgrade for her severely beta husband of 18 years. Her SMV is very low (read: 275 lbs) so alot of time & effort was needed, I shudder to think how many candidates were "interviewed". Even still-half-beta exbp was approached but luckily I saw what was happening and can't deal with the land whales. I hinted as strongly as I could to hubby that he needed to man up and open his eyes but he continued to believe the Disney version. She finally finds one and kicks hubby out and moves new guy in. But new guy is nearly as beta as the old and has even lower SMV.

What gives? He makes 3x the money as the old guy. She ruined the lives of her man and her kids for an extra $60k / year.

Lessons: Keep improving as many angles as you can. Your SMV isn't the only factor. Your little snowflake will fuck around for years if she thinks there's an upgrade at the end.
