Fight with my girlfriend..

You should get her a small gift and apologize. Try to be more understand of how she is feeling if she says that your not understanding. But if you get her a gift I'm sure that will make her feel better. And let her know that you will work on whatever is bothering her.

Girls are so moody. You should ask her what is wrong with her and what is her problem. I myself would eventually become so moody when I see my boyfriend doing nothing and acting like nothing. I just fight him and tell him I am angry at my boyfriend. Then my boyfriend would say sorry even if he didn't do bad. He's just sorry for his incapability. I forgive him though.

i think not only you had experienced it slow down wait until her anger is slow down and you must talk with her from heart to heart

I think her problem is that you don't understand what she is talking about. Men and women think different. Since I don't know what she said, or tried to explain to you, I can't help you with it. Perhaps you can make a list about the conversation/fight you had, what she said? Try to re-read it and read between the line. Many times A is said but B is ment. It won't help btw to keep repeating that she should say what you did wrong or said wrong since you already don't understand what she is saying and she keeps repeating you should understand things. I assume this has to do with things which are normal to her to understand at once. Give it some room, don't ask her anymore and if you really feel sorry(about the fight) say sorry in some time. If the air is more clear perhaps you do understand what she is talking about or she is less upset so you can talk about it easiler. Clear it is to me she is very annoyed about your behaviour at this moment and you only mae it worser if you keep saying: I don't understand it.

Perhaps it is time to move on. If not give her a few days to a week without any contact to see if she initiates any contact with you. If she fails to do so, then you know that's your queue to move on. You already apologized to her countless times before, so why keep throwing that her direction when you know she's unwilling to compromise. Again just give the lady a bit of time. Try one last contact in a bout a week, if she ignores you, or chases you off, then you know the drill....
