Or, for that matter, do the ghosting?

I'm not here to judge, I just wonder how common a phenomenon this is. It's happened to me a few times, and I wonder if it's just me, or is this just kinda how things are? I've gone out with someone, had that excited feeling due to the lively banter via text of phone beforehand, showed up and felt a big spark, and really *thought* it was mutual. And then after... [tv tuned to a dead channel].

Recently - within the past month - two times I went out with someone and had those big butterfly feelings during and after. The most recent instance was someone who I had a spooky amount of interests in common, like, we'd probably make pretty good friends even if we weren't a romantic match. But she's also substantially more conventionally attractive than I am, so I'm really not altogether surprised that in the end, she wasn't interested. It just ... seemed like she was? Typically I would not put someone on the spot by asking them out again during the first date, I feel like that can put undue pressure for them to say yes. If I want to see them again, I follow up afterwards and propose a specific activity that I think they'd be interested in. But in this case, she asked ME out at the end of the date, making plans for the following weekend. And then ghosted.

I figure maybe I'm just really bad at reading people's interest level, and I'm not successfully distinguishing between being polite and genuine mutual attraction. I also suspect that women, especially women who have had run ins with guys who react extremely poorly to rejection, may feel it's safer to just feign interest in person, and then avoid confrontation by just not responding to texts or calls. And ... I mean, I get it, we hear such horror stories here, I'm not mad or about to throw a tantrum or anything. I'm a little hurt and disappointed, of course, but not salty or anything. But after it's happened a few times (and not every time or anything) I wonder how common is this? Is this something everyone experiences from time to time, or am I exception, and need to take a good hard look at what I'm putting out there that's garnering this response? (Which I'm going to do anyway, as overthinking is my #1 hobby.)

What do you say, folks? "It just happens sometimes," or "It's just you"?
