first date post-divorce ended at a swingers club and i think i moved way too fast

so i met this guy on feeld, both newly single, both ex-LS. dinner went well, drinks went well, then he suggested popping into a club for a drink "to see the vibe" and i agreed bc honestly i missed it. we ended up doing way more than a drink. and now 3 days later im in a spiral. like did i undo a year of work? was i just trying to recapture something? does he respect me now or am i an easy story... i thought i was past needing that validation but here i am. is this normal post divorce behaviour... cork, ireland
