My girlfriend wanted to break up and see what's out there?

Er...initially I would've said that I can see where she's coming from ...roughly...she most obviously got slightly bored...but mostly saw what all other couples were up to and wanted to have a taste of all that before she completely committed. And yes, girls can get wierd like that sometimes, well, most times. And I'm gessing the "no matter what she's going to hurt someone" was...no matter what she does...she ends up hurting someone emtionally. This is what I got from it all. One thing is for sure...she wants you back :).She's had a taste of what's out there, didn't like it all that much and now turned back to realize you were also gone.

Don't take her back. The fact that she left you and "wanted to see what's out there" means that she was only thinking about herself. That is very immature and selfish. She called herself a big f*** up because she now knows that she threw away something that was very valuable to her (you). Don't take her back, because it looks like she will always be selfish after doing that. She should have been smart enough to recognize that you are human and not some disposable commodity.

She said "no matter what, [she] will hurt someone." That statement along with what she did to you means she treats all guy like they are disposable commodities and are replaceable.

Females. Intriguing creatures. They never know what they want and, in seeking what they think they want, always manage to ruin the one thing that was truly going good for them. This leads me to believe that they enjoy being or putting someone else through emotional pain. But back to your question, she fouled up and she knows it. You ARE the man. YOU are the best and she KNOWS it. Now it's up to YOU to decide if YOU want her back. Now that I pumped up your confidence, you have to follow your heart. But what do I know, I'm Just A Random Guy. Good luck to you, sir.
