My girlfriend is angry and doesn't reply to the message by texting.

If your girlfriend is angry and doesn't return your messages or answer your phone calls, you can try the following methods:

Give her some time and space: sometimes people need some time to calm down, digest and deal with their emotions. Respect her feelings, give her some time and space, and let her handle her emotions by herself.

2. Think about whether you know why she is angry: Think about whether you have done something that makes her unhappy recently, or what problems need to be solved between you. If we can find the cause of the problem, we can deal with it better.

3. Write an apology letter: If you can find out the reason why she is angry, try to write an apology letter to express your apology and your determination to try to correct the mistake. Express your true feelings in the letter and let her know that you value and care.

4. Find a suitable time: contact her when her mood is stable. If she still doesn't want to talk to you, you can try to find a suitable time, such as waiting for her to be in a good mood before trying to contact her.

5. Patience and self-confidence: No matter how bad the situation is, patience and self-confidence are the most important. Don't give up, trust your feelings and respect her decisions and feelings.

Finally, if the problem cannot be solved, we should respect her decision. If she wants to break up, we have to accept this fact and try to get out of this relationship.
