What should I do if I make my girlfriend angry and don't answer the phone or return the text messages?

So the point is, when did your girlfriend get angry? In fact, when your girlfriend is angry, for whatever reason, then you make a phone call and send a text message. This is absolutely correct. Keep calling. Keep calling. They will think that you love him very much, so don't send text messages, because you don't know what to send, because you send too many text messages, so keep calling until he answers the phone. If it really doesn't work, then you can go directly to her. This is the best way to solve the contradiction between you two.
