so this really good looking girl (i would say 8 maybe even 8.5, gave me her number about a month ago.
we talked on the phone couple times but mainly text. (she talks a lot, and when she text, she rights a lot!)
i dont see it as ioi, i think its the way she is.
now the problem is that we can never set up a time to meet up. i feel like she wants me to be her friend but doesnt want to meet up with me or she is test me how long can i wait without asking her to meet up.

ive tried about 3-4 times to meet up for coffee, a party i was at (and she was around) but always seem to fail. other times she "has to study for exams".

she is obviously not the only one im stuck on.. its just she is hot and i want her. (mean while im trying to do the same with 3 others)

a different girl, hb10 (no joke. big boobs, blue eyes, really good!) is playing with me i think. she knows i want her and uses it. i stop sitting next to her at the lectures but text her sometimes. last text i asked her to go out with me and she said she cant that day but offered to do something the next day, i said cool but told myself "if she doesnt call me tomorrow then she doesnt want it anyways".
help me guys, i feel like im getting numbers but nothing after it...

i feel you bro.

It sounds like you have pretty good text game, so dont think that your texts are the problem. Try calling the girls in person. In my experience girls are 70% less likely to flake on an appointment that they made by speech than by text. Talking on the phone also Demonstrates Higher Value. I gaurantee that the majority of guys she's met texted rather than talked to her; talking sets you apart as different and special. Second of all you have to accept that a certain percentage of girls will give you their number and basically no matter what you do, you will not get a day 2. Good luck dude.

i tried calling.. some answer some dont. if they dont i leave a voicemail message almost always or text something after 10 min.
they usually call back an hour later and we talk but we never end up meeting.

maybe its what im saying or what im texting that ruins the whole thing? i mean.. im trying to be funny and cocky here and there and they seem to like it but i dont know...

Okay, if calling didnt work here's a few other strategies that may help you.
1.)Build rapport! When you are with somebody in person you try to build attraction etc but over the phone at least for me the goal is rapport. Try talking about her tests, her schoolwork, life etc and do not always push for day 2. If you use this strategy when you push you should have better luck.
2.) Demonstrate Higher Value If she flakes on you, do not demonstrate any anger say "no worries", or "I have a party to go to that day anyway so my weekends still awsome" etc. If you show that you have a fun and happening life she's more likely to want to be a part of it.
3.) Use waiting game If she flakes on you do not immediately push again. Wait for a while to show that you are not that interested in her. In my experience, even if you push and fail, you are still likely to succeed if you push after using 2/3 weeks of not texting her or even responding to her texts.
NOTE
Waiting game is only effective if you have rapport. If you do not text some girl you dont even know for like 3 weeks and then suddenly text her it just looks CREEPY.
4.) Again calling typically works better than texting.
Hope this helps

Most of what I have to say had been said. but mystery says talk to a girl for a while to build rapport after getting her number (5 minutes from a cold approach)

I think your problem might not be AFTER getting the number (text/phone game) but BEFORE.

in other words, if this keeps happening IMO it's probably because you didn't make her want to hang out with you enough when you got her number. You probably need to Demonstrate Higher Value and build more rapport and comfort BEFORE getting her number.

Also, I heard somewhere (tyler durden I think) that a lot of times a girl won't meet up with you because she thinks it will be uncomfortable. You are inviting for coffee, which might be uncomfortable. Try inviting to a group setting or a setting where there is weed or alcohol or something else that's really fun BESIDES YOU. this gives her reason enough to believe that no matter how awkward it might get with you (even though it won't bc you are a pua with mad conversation skills, she doesn't and can't know that ) she will still have fun. get it?

Just some suggestions, try playing around with this stuff, i honestly think it'll help
