1. Text or call your boyfriend, but not too often. If your boyfriend doesn't reply for a long time, you can send a friendly reminder or a greeting message, but don't be too hasty or angry.

2. If your boyfriend's cell phone is turned off or the text message cannot be delivered, you can find other contact information, such as social media or other mutual friends.

3. If your boyfriend has a busy life or is under great pressure at work, you can understand and tolerate the reasons why he doesn't return messages. In this case, you can leave some space for your boyfriend and take the initiative to contact him when he is emotionally stable.

You can try to find out the reason why your boyfriend doesn't return messages, for example, because he is sick and busy. If you can understand your boyfriend's situation, you can take corresponding actions to help him.

5. Communicate frankly with your boyfriend and tell him that not returning messages makes you feel worried and uneasy, but pay attention to the way and tone, and don't blame him too much.

6. Leave enough time for your boyfriend to reply to the message, and don't be too impatient or assert that you have been ignored. We should also pay attention to reducing the information monitoring and interference of our boyfriend, and give him time and space to think and deal with problems alone.

In short, when a boyfriend doesn't reply to information, he needs to consider the problem from his own point of view and face it with reason and trust. Unless your boyfriend doesn't answer the phone for a long time or loses contact with SMS, you should give him enough trust and space.
