I posted here last week about going to my lovers party and not being able to be open about being the lover. This is a follow up...

I went. I had a great time. But I mostly didn't talk with him. When I did it was short and kinda awkward.

That said...there were a lot of ENM folks at the party. I didn't intend to stay long, but I did...and I wound up making out with several of them and having what I thought at the time was discreet sex with one...but lover walked in on us...

Now, I'm left wondering if ITA. For context:

• lover was also making out with others
• lover warned me before the party that things might get sexy and that he wouldn't be able to be with me if they did.
• I, however, did not check in about getting sexy with others...I had intended to leave early...this is where I may have gone wrong
• at the end of the night a bunch of folks there went to get sexy in another room...I was asked by lovers partner to leave for this bit (which is fine) and I left at this point
• I had sex with that other guy before others got sexy.
• we have checked in and he tells me I'm sexy and that he was a tiny bit jealous.
• lover had always told me he doesn't get jealous

I can't shake a feeling that I fucked up. I don't know if it's the many years of monogamy or if I really did. Please reddit, weigh in.
