so yesterday (saturday) i went out with a bunch of people, some collegues and some friends of theirs. on of my collegues is someone ive dated before, on and off. we ended up spending most of the night with our hands around each other, was a fairly good night. next day, my boss at work asks me if i was going out with another of my collegues, also one of the other girls i was out with that night. i laughed it off and said no. heres the shit part. i messaged the one i was with that night, saying that my boss had asked me this. she didnt reply. was it a mistake to mention something like this, even in passing? i wouldnt have thought it was such a big deal since she knows im not interested in this other girl.
