My girlfriend suddenly got angry and sent me a text message.

Under normal circumstances, couples quarrel, because of problems such as face and small self-esteem, both sides are unwilling to bow their heads and admit their mistakes, so there are more and more contradictions.

She is angry with you because she wants you to improve. Girls don't like boys addicted to games.

Now, you can reconcile unconsciously, instead of saying that you are wrong and making you admit your mistake. Girls show that they don't haggle over every ounce

She gave the steps, so she got off at once.
