Maybe I’m just an old-fashioned grateful person, but when I was single, and a guy showed interest or approached me in a respectful way, I was flattered. It didn’t matter what he looked like, even if he looked like Shrek, I’d take the damn compliment. And if I wasn’t interested, I’d at least be gracious about it which saved him face, and me from looking like an entitled bitch.
Flirting used to be a wonderful courtship ritual, now it’s turned into a minefield. A battlefield is more like it. And that's a shame.
If we need "signals" it’s only because everyone’s so busy either hating on each other, being guarded, or they’re deathly afraid of rejection.
Men: Approach in a respectful, non-threatening way.
Women: If interested, be receptive. If not, at least give a guy credit for trying.
Since the dating power dynamics are shifting,
Women: Assert yourself and make the first move.
Men: Be appreciative, even if you're not interested.
Best of luck everyone!
