I met a girl visiting my city, lots of kino and mutual attraction but couldn’t close. She said she had boyfriend.

She contacts me after she returned home to buy something I make, I flirted while she didn’t respond well that much yet didn’t reject my advances either.

Realized I was orbiting her and nothing else, stopped paying attention to her. Now she texts me every few days, one of them saying she had a dream about me, is stalking my instagram all the time.

I’m not sure if she’ll text random shit again to get a reaction, but how to proceed if there’s even a bit of desire in her to see me again, without giving her validation for free?

Note: We’re texting over email and I don’t have her number (I suspect because she wants to keep it secret from her boyfriend)
