used by a couple who played twice and then ghosted into the ether

me and the wife met this couple in auckland in march. clicked properly. dinners, drinks, two amazing nights, the kind where you're still messaging at 3am the day after. we honestly thought wed found friends not just play. then nothing. read receipts. story views. no replies. saw on insta they've been hosting half the scene since. it shouldnt sting cos we're grown adults but it does. wife is gutted she really liked the other woman. i feel like a teenager whos been ghosted after the school disco. is this just how it goes... do you build a thick skin or do you stop investing emotionally and just have surface sex with strangers. mid 40s both of us, six years in the scene
