right?

What often are petty reasons from a man point of view... are big issues for women. So as I don't know what you did or said... I cannot tell you what to do. Obviously... you care enough about her to run after her. So from a general point of view... apologise to her for what you did. But don't crawl. If she is not big enough to accept your apology... tell her it is over and walk out. This is called "bluff". You put the ball in her court. If she cares about you... she'll have to start to do a bit of running of her on. If she don't... you better off without her. You must never crawl... because she will like that and she will make you crawl for the rest of your life.

It sounds like there's an underlying reason for all the anger. Maybe she's stressed out about bills, money, work, her family? Sit down and talk to her and tell her you're there to listen to her, but she has to stop running away from you and getting angry at you without telling you the real reason. It could be that she's afraid to tell you something, women often fear being open with their significant others for fear they'll be judged (remember, women judge other women ALL THE TIME). If she keeps up the behaviour, then it might be best for you to break it off. She obviously needs to mature a lot more before she's ready for a long term relationship, and she needs to learn to vocalize what she wants and what is bothering her before she's ready for one. The only reason I know this.. was because I was identical to your girlfriend. I was not cheating, I was not lying about something, but I was in the worst trouble financially and didn't want my boyfriend to know for fear he'd think I was bad with money and irresponsible. After we broke up, I was forced to sit down and think over what it was that drove me to acting angry with him, and I found it was frustration more than anything. He always told his family and friends how proud he was of me for taking care of things at home (bills, rent, etc) and I felt like it was all falling apart on me. I never wanted him to know how tough it all was, so I got mad at him for not helping with chores, not playing with his kids or calling at the exact time he said he would because I wanted to draw his attention away from it. I didn't ever tell him, since we split on very bad terms (he cheated), but I know better with my new boyfriend.

The only time I would recommend running off after a girl is when maybe your guilty of doing something wrong but if she keeps getting mad at you for stupid or little reasons Id let her go and come back to you or she'll be doing that all the time you's are together. Also if shes starting fights with you or stupid sh*t then she might be guilty of cheating or something like that because from what you say it sounds like shes trying to make you mad or something to break up. Just keep your eyes open and dont run after her unless your in the wrong. Good Luck!
