Girlfriend doesn't return text messages or answer phones when playing games.

If you care, keep it in your heart, be wronged for a while, and ignore her for a while. Of course, you are not ignoring her, you are moderate! The more you care, the more you feel that you are the person you care about in your life, so no matter what you do wrong, right or hurt you, because you love her, your paranoia will tolerate her! Don't quarrel with her, don't do meaningless things, quarreling can only hurt each other's feelings and have no effect.

Since she won't answer your phone calls or reply to your messages, you will (occasionally) answer them. She won't do this until she has experienced that feeling first hand. You know this is an invisible injury!
