You show signs you like her and see how she responds. You write like you want women to offer themselves up and you pick which one you want. Nah… You offer yourself and see if she’s into it. Be subtle enough she’s not sure if you’re interested at first and ramp up until presence or lack of mutual interest becomes clear.

If the vibe turns sexy awkward ask her out. If it turns icky awkward just stop. Letting her go gracefully when she’s not into you is key. If you over invest or don’t drop it you’ll get labeled creepy.
