She's just not into you or is she?

So guys, you met this girl at a bar/club/lounge, exchanged numbers, waited a few days to call but wtf, she never called you back!
Why did she give you her number in the first place? If she gave you her number that means she was interested in you right? Oh naive silly lil man, you should know by now that its never that simple when dealing with the female gender.

Reasons she gave you her phone number:
1. You asked
2. She was drunk
3. She didn't think you'd actually call
4. She really was interested in you
5. She really wasn't interested in you (refer to #2)

Reasons she didn't call back:
1. She was drunk and doesn't remember meeting you
2. She was drunk and is ignoring you out of embarrassment.
3. She enjoys the game of flirting (number exchanges included) and game over corresponded with last call.
4. She's passive-aggressive and instead of saying no or coming up with an excuse, she decided to give it to you and just ignore the calls instead.
5. She was interested but her friends staged a beer goggle intervention.

So guys even if you think she's interested, there's always the chance that....
she's just not into you!

PS. If she doesn't call you back the first time, most likely she's never going to and your repeated calls aren't going to make a difference (besides make you appear like a stalker) so accept defeat and move on to the next complicated and confusing gal. ;)
