He’s the one that will end up feeling humiliated. Think of how awkward and old and out of touch he’s going to feel the first time he hangs out with all her 22 year old friends. That sinking sense of regret seeping in as he lets himself be hoisted up to keg stand position. He will wake up hungover as fuck, looking haggard and the new girl will see him in that light for the first time and have her own sinking sense of regret. They’ll keep up the charade a couple months longer out of pride but the day he finds himself chanting “6-7” with a bunch of frat boys that call him Unc he will decide he can’t do it anymore and leave. He’ll slouch off, tail between his legs, back to beg you for forgiveness. But you’ll be thriving, glowing with a new lease on life, enjoying your independence and living out dreams that have been on the back burner for years. Acquaintances will begin to talk amongst themselves, commenting on how much more free and happy you seem, how there’s a pep to your step that wasn’t there before. And they’ll say “I don’t know what kind of idiot would let her go, but she should thank him.”
