A couple of things from the female perspective.
1. IF she had high interest, she would have responded to your text.
2. If she had romantic/sexual interest, regardless of what she does for a living, she would
not have been too bothered that you build surfboards, she would have at least wanted to know more (i.e. if that's what you do for a living or just a hobby).
3. Re: you reading signs she is attracted, IOIs? What were these IOIs? I only ask because I have had plenty of instances where a guy misinterpreted my being friendly as being "attracted" when I wasn't.
So just curious what you're experiencing?
Why don't you ask her out one-on-one? Coffee, a drink. Something low key and inexpensive. Or even just a walk someplace cool which costs nothing.
OR better yet, you could play the long game and wait to see her at the meet ups.
Personally I
love that type of long game, the tension, the uncertainty. There is NO rush, you shouid have other options and you know you will see her again.
Bide your time and let her wonder about you a bit. Whether you're dating other women, what YOUR story is!
Use a lil push/pull - sometimes you talk to her, sometimes you don't and are off talking with others.
Act confidently and
let her wonder! I am experiencing this now and my interest went from "meh" to "yeah"!
Let her find her way to you! Which she will IF interested, it's instinctive.
All this should be fun man! I think you may be overthinking this too much and it's getting in your way.
Just my take, good luck!
