I stopped chasing numbers for a while, but yesterday I met a cute girl who I was attracted to and we exchanged some witty banter, made some physical contact and before she left I made sure to get her phone number. I wouldn't have went for it unless I was absolutely sure (there is really no definitive way to be 100% sure, but I was confident in her attraction towards me) we made a lot of eye contact and smiled a lot, after a while she spoke to me first so I am confident at this point she is attracted, this doesn't really mean much in terms of results, shes obviously somewhat interested but I need to have some strong mid-game to progress things.

I am quite weak in this area, and would like some other guys thoughts on texting her so that I can move things along. Here is our brief interaction so far.

Me: (she gave me her number and did not have mine yet, so later at 1:00 pm about an hour after she gave it to me) Here is my number, I'll text you later when I get some free time. It's Michael in case you forgot already You're absolutely adorable btw. (might be to much oh well moving on, id like thoughts on this, all advice is gold in my books)
Her: Lol, hey. I didn't forget...and thank you, that's nice.
(so about 11 pm)
Me: Finally got some time, when are you free this week? (might have been to soon, but I didn't want to beat around the bush, I hate the fact I am actually over thinking this by coming here, but I want to learn from this)
(next morning today)
Her: Morning, I'm kinda busy this week. So. Idk. (not sure if this is a shit test, or she lost interest, either way I think to truly find out, I need to come at her with some stronger game and show her my value or alas figure out a move to pass the shit test she's most likely using here, which is something I need to work on hence the grief)

So I am open to thoughts/opinions whether they are harsh or kind, let's go!
