I met another girl (#2) while being in a LTR and have been vetting #2 for 7 months. Broke up with previous LTR in month 4 and continued vetting #2. She cooks, sucks, massages me on demand; fully into my frame and submissive (even while I was still with previous LTR). Didn't LTR her but so far seemed to be a high quality woman with good values. For context my SMV is high - successful entrepreneur (in the press, etc...), lifting daily, etc... have a lot of options and she knows it; always saying "that it's clear I'm willing to walk at any time".

I set clear boundaries about honesty and transparency, and that I don't tolerate lies. She previously mentioned breaking up with her ex at a specific date (mid August 2020), but I have evidence (photo from a lost Instagram post) that they were doing some outdoor activities with friends and holding each other like a couple would for a pose i.e. likely were still together at least a week later than she claimed.

Now this is all inconsequential - it was before we even started chatting and while I was still dating my ex. The action doesn't matter at all but I don't tolerate any type of lies and have no interest in keeping her even as a plate if she did lie.

I asked specifically about this hike (she had spoken about it before) and while she was transparent in saying that they went together with friends, she claims that they were broken up at that moment (despite holding each other on a photo).

I ended things without mentioning the photo, saying that my gut was telling me otherwise. She maintains that "she was there and knows what the truth is" and that they were not together anymore at that moment but that she couldn't change my gut feeling if it was like that.

Am I overdoing it? It could be that they were just posing together because the break up was fresh. I'm relatively invested because I have been vetting for multiple months but have no issue walking away. Would love some alternative perspective.
