Boomer,
I completely agree with you that most new people shouldn't go online to start persuing women until they gain some experience. It can be difficult to read between the lines so to speak and see IOIs or IODs. I have written a few ebooks on online game and it's my personal suggestion that most people spend time in field before going online. When you get better at recoginizing patterns with women then it's easier to convert those lessons learned to online game. But anyways, I'm not trying to lecture just agree with you.
It's awesome that you spoke with her for almost an hour. Her statement,
"haha no i missed it. i'm sure i'll see it eventually" is a good IOI I'm sure you'd agree.
It's hard to tell if she was just really in a rush to do something and get offline and didn't see your message or if she just avoided your message.
One thing I'd like to critique here is the way you asked for her number. You said
"I gotta go now too we might throw something this weekend would you like to call or text you if something is happening"
I like the fact you gave her a good reason for her to give you her number. The thing I'm not so keen on is that you asked her to give you her number, you didn't tell her to give you her number.
When people are presented with a Yes or No choice the decision is usually No. The reasoning for this is simple psychology. People like taking the path of least resistence. For example, when you were younger and your mom said, "Hey Boomer would you clean your room for me?" What did you do? Did you clean right away or did you slack off. You slacked off, because its easier to do nothing than something. The path of least resistence is usually taken when given the opportunity.
Believe me I discovered this when I worked in car sales for many years. I knew they loved the car but when I asked them a question like that I usually got a No. But when I told them to sign with confidence I did much better.
Now that that lesson is over make sure to exhibit confidence and tell her to give you her number. Not forcefully but something like,
"Give me your number and I'll be sure to message since we're about to set up another party." Which sounds more confident than,
"Would you like to..."
I know you're still learning so I really hope this helps out. As far as not getting her number this time. Don't sweat it. Just look to talk to her again on Facebook. Keep talking to her and letting her in your world with stories and information about yourself. Basically, just building some comfort. Then ask her for the number again with confidence!
Cheers,
