Well based on how TS framed it..
All framed in his mind.
Well, my experience has absolutely been that women tend to be embarrassed or for whatever reason hesitant to acknowledge that they have initiated pursuit of a man or even pressed the issue. I can think of multiple times where women, especially younger women, who were clearly pursuing a man would relate the dynamic between them as the inverse of what it was, with them being the passive object of the man's desire.
A girl comes to mind who I knew from work and the gym who had given me her phone number--unrequested--and made fairly unsubtle overtures towards me a number of times, who had also provided her number to a friend of mine. If memory serves, I also saw her engage in some of the same behaviors towards my friend that she did towards me, stuff like running her hands along your arms, etc. When she talked to me about my friend, she claimed to me that he had creepily been texting her to workout together at the gym, etc. She completely reversed the dynamic between them in her narrative.
I can also recall another girl who was borderline obsessed with a coworker of mine, but whose advances were always rebuffed, who, years later, talked about what a huge crush the poor guy had on her, etc. And I used to work with both of them mind you, and would hear the girl go on and on about him, not to mention witness her constantly coming on to him.
Granted, I can actually think of guys that were like this as well; there was a fellow who was obsessed with my twin sister, who was so disinterested she didn't even ever want to be with him alone. Similar to the aforementioned women, he'd later talk about how my twin sister used to have this huge crush on him, when the fact is that she just thought he was weird but relatively harmless and didn't want much to do with him.
The main thing that was weird with OP was talking about the girlfriend dating a black guy as if it was some knock against her credibility. That was kinda off. But I could certainly believe that he was friendly to a younger woman and cast as someone who was hitting on her.
