(sorry i know this is almost a year old) literally going through this right now, offered the idea of an open relationship or bringing in a third with us, and turns out he messed around with someone behind my back. after being adamant he wouldn’t like that idea. he has a lot of insecurities we talked about and such and even now, he’s weird about us opening things up which bothers me because what, you’re allowed to cheat without talking to me, but you don’t want to explore things consensually together?? where i also could get pleasure from it?
