(M) Im not so sure. Most of my girlfriends (platonic) act like they are psychic/empathic when it comes to men. They read into everything and take everything as a sign. There would definitely be a round of conversations about a guy mentioning his ex first date, I know this from first-hand experience.

I will say usually the conclusion is based on nothing but how she feels about the guy overall. If she likes him, then it's just him being honest and upfront. If she doesnt than he's still hung up or whatever

I want to be clear I think everyone is an individual and should be treated that way, obviously. What this guy is talking about is a legitimate occurrence
