When my BF and I first started dating, he came out to me as bisexual. Seeing as I was very openly pansexual, I suggested that if he ever wanted to be with another man or woman while we were dating, I would support him, so long as he did the same for me if I ever wanted to be with someone else.

Several months went by, and both of us had just pushed that agreement to the backs of our minds because we were so busy with other things. When we last spent time together, he confessed to having slept with one of his friends [M] the night before. He told me he regretted it afterwards and asked me how I felt about it, and I told him I was fine with it. It is now several days after the incident, and part of me regrets saying that because it feels like I'm disregarding his feelings on the matter.

I just need help figuring out this whole open relationship thing. I suggested it with the idea that the two of us could have sex with someone we found attractive if we were not available to each other. But, if he regrets having sex with someone else despite being in an open relationship, should we actually be exclusive?
