Yes, you're coming across as needy and too available. Leave it for a while. A week or so, just be silent.

Stop asking questions in texts, this is needy. Just make short statements, ideally provoking conversation that she's interested in. You can talk about your own passionate interests face to face.

No smiley faces. Only gaylords use these, it's a nervous way of transmitting the underlying tone of your text because you feel the words have so many ways of being misinterpreted. Leave it, she knows what sort of character type you are if you've already met. No sweat.

Remember that encounters can take weeks and months. I met a girl for literally 3 minutes, 4 months ago, and due to random clashing commitments and long distance until recently we've still not managed a 1st date yet. It's not really an issue though.

Get more girls, the more girls you get, the more girls you'll get!
