SXSW was a little while ago, but I spent a lot of time during that week in downtown at bars, watching shows and drinking. I'm 21, have a full beard that I keep groomed, so I often prefer to talk to women that are a little older than I am because I click a little better.

I was at one bar and this one girl I found really hot was making eyes with me for a solid 3-5 seconds. I wasn't in the best head space, so I didn't act on it immediately, and I had to psyche myself into approaching. I did, I learned she was 29, she told me I was a baby when I said I'm 21 and I told her she wasn't the first one to say that lol. Conversation was decent but short lived, her friends wanted to leave, apparently. It could have been her trying to escape or actually the truth, but it didn't matter to me too much, I was happy I pulled an approach for the first time in a little while.

Later that night I was with my friends taking gear back to the van (they're in a band) and I was approached by a girl who I thought to be an 8 or so. She was really into me from the get-go, she was laying the compliments on heavy and early, she held my cigarette for me when my hands were full, and we wound up on a couch somewhere making out an hour later. We exchanged numbers and she said we should meet up, and she told me about a couple fetishes bla bla bla. Night ended well.

This is where the lesson is. I texted her the next morning. I could tell immediately she wasn't into it. Her replies were lame in comparison to how our dynamic was, and eventually she just ghosted me completely. My lesson learned here was that the courtship doesn't stop, and that building anticipation and creating ambiguity are key even after you've managed to close to some significant degree. I've noticed in myself and many other guys, after they feel they've gotten her, they show all their cards too soon. What I learned and what I feel everyone should remember, that when she starts to like you, disappearing for a little bit and letting her come to you goes a long way in making her like you more and not get bored with you.

Sorry for the wall of text!

TL;DR Women will get bored with you even if they're really into you. If they're into you, make them chase you a little more, they'll do it anyway
