Girlfriend is very angry. She is very traditional, conservative and simple.

Everyone has his own little personality. If you love each other, it's nothing. If you love someone, you must tolerate everything about her. She is the kind of person who is petty and doesn't know what she said, especially when she is angry, but she will definitely regret it afterwards. You shouldn't have quarreled with her at that time, but should have tolerated her first. It's wrong to tell her something when you are in a better mood afterwards. If you quarrel with her, she will be worse than you, so as a man, give in a little.
