Well what the heck??

My boyfriend and I have been together for a year and a half. We are really kinky and like to try a lot of different things. We decided to try a foursome but had a bad experience with the couple HE chose. I had found one before but he didn’t want to meet up with them even though they were really good looking and wanted the same things we did. Anywho we sort of started fighting Friday night over something and he said that he didn’t want to be in a monogamous relationship which I already knew. He likes to have sex a lot. He said that sometimes he really wants sex with me and other times he wants someone else but feels bad if he does anything without me. He also kept saying that he doesn’t get jealous yet part of the reason for why we were arguing was about the couple we met up with. They contacted me behind his back asking if I could come over and have a threesome with them (I said no and didn’t want to do it). We talked about finding other people but then today he says that he doesn’t want to try again. 😑 Part of this was his idea and he was all for it constantly texting me when he found someone he liked and now he just doesn’t want to do it anymore. It’s just really confusing because he did all that talk about how he wanted us to be able to still occasionally hook up with other people and wanted us to try a lot of different things. I just don’t get it...
