Hey OP, I hear your frustration. Sometimes, she will simply not be into you like that, and that’s okay. But there are concepts that can significantly improve your dating life if you learn them.
The most important thing is to intentionally be romantic. **You have to flirt. **The way you describe this interaction doesn’t sound very flirty. She was nice and you had a good conversation? That’s great, but she could probably get a similar experience from a friend.
Flirting is about making things exciting. Taking a risk and making your intentions known is often attractive. Think playful banter. Having a low stakes, interview-style conversation is just boring for most women.
Practical ways to be more flirty:
choose a venue where you can sit side by side
maintain great eye contact when she’s talking
don’t rush to fill every silence, let it breathe
use statements more, rather than just questions
respectful and appropriate use of touch
playfully challenge or disagree with her at times
humor is great, but don’t constantly joke around
Basically, being a nice guy with a good job is great, and actually a prerequisite for many women to date you. But it’s not inherently sexy. You gotta learn how to embrace your romantic side to show them you’re capable of that, too.
