I am just curious if I should be more concerned or upset about this situation.

I don’t actually feel upset but I do wonder if I should be more concerned and would like to hear some perspective from this community.

For some context, this is a wlw relationship. My partner also has a past of cheating and hiding it from previous partners.

Going into dating me, she was very open about it with me and had intentions of being honest and ethical moving forward, hence why nonmonogamy appealed to her.

I also had experience in nonmonogamy and appreciated her honesty about her past, especially because it was a risk to share with me early on.

Anyway we established our boundaries were mainly about honesty, telling one another about dates, or things that turned more than platonic, basically being forthcoming and never hiding anything.

We are 3 years into our relationship now, and in passing something came up from the beginning of our relationship, about 6 months in. She had brunch with some friends and got drunk. I remember this day because I had plans with her after and she picked me up from work and was more drunk than I anticipated. Anyway I found out just now that during her brunch outing after some of the other friends left, her and another friend kissed and were flirty with each other through the brunch. It was said casually and kind of grazed over and I had to stop and ask because I realized this was something that occurred during our relationship that she never told me happened. Technically this would fall into something that I should’ve been made aware about according to the boundaries we discussed. She said she never intended to actively hide it but rather it never registered as anything legit, this friend was always kind flirting with friends and trying to kiss them, and she just thought they were having fun.

It’s not that I feel hurt or threatened by that action, but I’m a bit bothered that she never told me about it. I wonder if I should be concerned about this being a small glimpse of what could be bigger and what could be a repetition of her past on me.

Any thoughts?
