I spent a good hour talking to a girl, built up some comfort and rapport.

Throughout the conversation I received a lot of IOIs from her. Constant eye contact, smiling, re-initiating conversation, asking questions...

She had to go home relatively early and when she left I said "I'm gonna see you again soon hey?". She replied "Yeah definitely!".

Now I didn't number close her, the logic here being that I would send her a facebook message later in the week. Facebook for the girls around here is more casual and less of a "forced" obligation, if I could put it that way.

I sent her a message, "It was nice getting to know the real you!" (referring to a conversation we had. She didn't reply to this at all.

Now onto my questions...
Did I play this right?
Am I wrong by basing most of my interaction over facebook? (as opposed to getting a number)
Where do I go from here?

Any thoughts at all?

You should have number closed.

err on the side of number closing earlier next time.

next time she's on FB chat shoot her a chat or something

"I think i'm pregnant" (depending... ehh... idk.. i just think it's funny)

"You look like you're up to no good"

"If it came to a physical confrontation, who would win? a Kitten, or a Smurf?"

If not, def. number close next time you see her.

P.S. Absolution... Amazing!

I can't figure out how to get an avatar picture.. it wont let me... sad day.

Thanks for that, I'll definitely give it try... It's most likely gonna be a while until I see her again, so it's just kinda frustrating.
