This girl I've been going out with recently, H (19F) and I (20M) were out having dinner having conversation like normal earlier today. I was recalling this event that happened around a year ago and my girlfriend at the time was involved, but I made a white lie and said that this person was only a friend. Gf at the time and I were together until around November last year, and H and I have been seeing each other for a few weeks though we have been friends for longer.
Should I have been honest and said to H that this was my girlfriend in the scenario? I know it's really not a good idea to bring up an ex especially to someone you just started seeing, but I feel like I'm being dishonest if I don't, especially since we go to a small college where they could easily run into each other.
TLDR: unsure about whether or not omitting my girlfriend from a story while talking to my current partner was the right thing to do.
