So, I gave out my number to several chicks on this dating site, right? I haven't been on a date for two years - focusing on myself and raising my value, so to speak. I'm feeling confident as fuck, but I think my game is a little rusty. Anyway, one girl gave me her number back, told me she was a big texter and to get at her. I kept the text conversations real short - some basic "getting to know what you like" kind of shit. She tells me she really likes Italian food, so I do my homework as to what's in the area. A few days later, text convo went like this on a Sunday:
Her: How are yooou?

Me: Sunny side up despite the weather, luv. How are ya?
Me: I just made pancakes so epic that there shalt not be anything like them four score and seven years from now...
Her: Hahaha ohh I'm jealous!! What kind of pancakes did you make?
Me: Chunky Monkey pancakes with bananas, chocolate chips and pecans
Me: But, don't worry. I'll be cooking breakfast for you eventually...
side note, I really didn't make pancakes, ha!
Her: Ohhh that sounds awesome! Hehe I can't wait

Me: So, I really want to treat you to an Italian dinner something fierce. Not sure if you're seeing anyone right now, though. Interested?
Her: I'm not seeing anyone no worries! And yes I am most definitely interested

Me: I was thinkin' (insert nice and casual Italian restaurant), Friday at 7:00? I'll meet you there
Her: OMG I love that place! That sounds perfect!!!!
So a few more days roll by. I really didn't text her that much because I was actually very busy, but she was trying to ping me alot. I also didn't want to know too much about this chica or want her to know too much about me over text convos because I'd be shit out of things to talk about on this initial meeting. Today is Thursday and I called her after I knew she was off work to confirm the dinner. Kept it right to the point, "Just thought I'd call ya for once, looking forward to seeing you tomorrow night." She said, "I don't know if I can make it, can I text you back in a little bit? I'm on the highway." Half hour later, text convo went like this:
Her: I'm waiting to hear back from my mom about babysitting my brother but I'll let you know as soon as I know

Me: Nevermind Friday then. Saturday night at 7? Or, shit, let's hang out tonight
5 hours later
Me: Haha! I suppose I should take the hint and cut my losses. Hope you find a guy that will treat a beautiful woman like yourself as you deserve! Take good care of yourself!
She hasn't responded, and I don't really expect her to. On to the next one, haha! She could've been telling the truth, but I had a gut feeling that she was trying to flake on me. Did I over-react? Maybe I should have set the date earlier? I don't know.
I probably would still take her out because she's a little spinner, but if she texts or calls back, how do I handle this? Ignore her and just keep chatting it up with other chicks? Or, should I take her out when she really wants to?
Thanks! If there's any other information I can provide, let me know. I appreciate the advice!
