Why Is My Girlfriend So Mean To Me When She Is Mad?

I'm sorry man but the answer I just read is terrible, maybe it's true what shes saying about expressing emotions verbally, but girls do have brains  and they can control their anger, try talking things out with her and really telling he what you feel about it. Tell her how much you love her and how much you want the best for a long lasting relationship (if that's what you want). After you do and everything seems like is back to normal, don't get too excited she won't change over night. She might have another breakdowns, your job is to make them less, and eventually she'll just stop. If things do t get better I suggest you distant yourself away and make the decision o either breaking up with her or continue in your relationship. Remember that breaking up can save both your lives from future misery

Maybe you should try to make her Very Happy

If this is a boy, your girlfriend is so mean to you because that is what women do when they are pissed. You have to understand that women have a different, more vindictive way to them, we tend to not express our feelings physically but verbally and we try to attack the mental aspect of a man. To men we seem complicated because men are like lets fight, get it over with, and make up.  Women are more like let me make him suffer as much as possible,  until we feel satisfied. And unfortunately for you your going to have to be prepared to deal with that every time she gets pissed (it is our nature), if you love her eventually you will develope a strategy to minimize your discomfort.
