My girlfriend got angry because of a little thing, didn't answer the phone, didn't send a text message, and came back for two days without news. I wonder what she thinks.

Hehe, relax. Maybe she's testing you. Maybe she just wants you to worry about her and know the value of her existence. Occasionally, in the dead of night, send her a short message. As long as she doesn't turn off her phone, she still wants to hear from you. Your information is very important to her. Get to the point. One or two affectionate messages were enough to move her. Just try it. . .
