I’m bi and he knows this. He’s always mentioned the thought of seeing me with another woman would be hot which I had no problem with. Later I had this coworker I was really into. I ended up entertaining his idea and showed him some pictures of her and asked if this was something he really wanted. He started to get really excited and agreed. Afterwards we started making plans I went over the ground rules with him. I told him anything is fair game but his (thing) cannot go inside her. There can be bjs and make outs but he can only be in me and the other girl can do as much as she’s comfortable with. He said he wanted a more involved role which kinda upset me because he’s only ever said he wants to SEE me with another girl not BE with another girl. So I decided to ask him if that’s what he wants then I feel like I’m entitled to a MFM threesome and he immediately shot it down so I said no deal and we got mad at each other for a while. I gave him my boundaries and he fought back insisting he gets to f another girl with me. It took some time but we calmed down and agreed it’s not going to happen. However the whole thing still rubs me the wrong way. I can’t get over the fact that he admitted to wanting another girl besides me and it doesn’t help that he still brings it up on occasion. I always say no or ask him some type of question and his response always results in me feeling worse about him wanting this. I need advice on how to get over the anger I feel because these conversations never leave my mind. Or maybe I should try to find a way to give him what he wants since he keeps bringing it up. But in all my research I haven’t found a way to make this happen without making us both happy. What should I do?
