Pushing people away by accident?

So the other night, I decided I needed to go out dancing - there were tentative plans to meet up with a girlfriend but nothing was solid. I decided to go on my own and see what's what. Ended up not meeting up with my friend - but instead jumped into a circle for colleagues I knew from school.

Anyways - all this means that I was in a dance club kind of on my own... a new slightly weird experience. On the dance floor I started letting loose, closing my eyes and moving to the music - letting go of stressful thoughts and being present with the movements and beats. It felt good!

Being on my own allowed me to look at the social dynamics on the dance floor in a new light... Saw this one girl just consume this guy with flirtatious looks - like she knew what she wanted and then she went and made him dance with only her. It was pretty impressive honestly - even though it was overwhelming to witness. When a shy guy was trying to come up to me - I waited for him to be direct and show his interest. I didn't want to play the role of the seductress - I wanted to be seduced... Since he wasn't brave enough to actually look me in the eye and get closer with movements - I stayed in my world of one and pretended I didn't notice his attempts of getting closer.

It wasn't until I got home that I realized I pushed away a possibly a-okay guy for no real reason. I essentially built up this wall around myself and didn't let this guy in because he wasn't willing to put himself out there. I expect a lot from my partner - evidently, bravery is right at the entrance of my expectations. Should I try to explore ways to become the decisive woman on the pursuit? Should I follow the 'He's Just Not That Into You' approach of letting a guy be the one who should know what he wants and showing it? It's a tricky game with no real answers...

Readers - if you're out there - I'd love to see you weigh in with your opinion!
