I don't think any harm was done. She wasn't too keen sounding and you never really made a move. Then its ends up she has a boyfriend anyway. You could have gone charging in and asked her out but the result would have been the same -she wasn't up for it. Sometimes we can work things out without needing to ask.

Another time she might be keen, especially if she has split up with the boyfriend. Sure to some extent she will match your energy, so if you are upbeat and confident, she will have confidence in you but it also never hurts to read her energy. If she is not keen, then a pleasant chat is good. There might be a next time.

"Not bad" depends on your language, In French for example its not a bad thing at all to say. Its a bit understated but its heaps better than "I think you are a awesome" (and I will be a massive simp). There is a lot to say for being understated. Women always want big compliments -so let them work for them. Why not let her know you like her and also give her the idea that you know there is more out there that either she or others could bring? An understated gent is not bad at all.

The supposed happy medium she's looking for is a fantasy starring herself as the main character, where all the hot men are written to be smitten by and motivated to cold approach her, while the ugly ones instinctively know their place as background props.

In reality, those top 10% hot guys that catch her eye at the coffee shop seldom approach a complete stranger these days because they're usually already getting pussy flung at them just from acquaintances they meet organically through work, hobbies, and other aspects of their life. Even if they happen to have room for an extra fuck buddy or two in their weekly rotation, Tinder delivers much more reliable results when you're that hot, compared to rolling the dice on any random stranger.

The song and dance she's daydreaming about is an outdated custom that doesn't make sense anymore. The most attractive men no longer need it, and for the others, it has become a humiliation ritual. She can approach men herself if she's that desperate to be Chad's Tuesday fallback option.

There are a lot of lonely people out there, desperately hoping/wishing that someone would take a moment to acknowledge them.

I would hazard a guess it's mostly Men being affected, although it is now being framed as a Women's issue because they are currently experiencing the swing of the pendulum in their direction, and they do not like it.

Men are branded with a lot of, mostly, negative labels by Feminists. It is difficult to reconcile that International Mens Day https://internationalmensday.com/ is shared with World Toilet Day https://en.wikipedia.org/wiki/World_Toilet_Day and still feel valued by Society as a whole and Women in particular.

I'm glad to be Married, if for no other reason than it meaning I don't have to face the challenge of trying to find a friendly Female face in a crowd and be branded.
