Break up with my boyfriend during the cold war and ignore him. He sent me three messages at noon, afternoon and evening. I'm just saying I'm sorry about what happened. How can I explain it to him?

If you want to give your boyfriend an explanation, here are some suggestions that may be useful:

1. Honesty: Apologize to him and tell him why you didn't reply to his message. Let him know that something happened to you, instead of ignoring him on purpose.

2. Express your feelings: Let him know that you feel guilty and sorry, because his care and love are very important, and your failure to reply to his message in time may make him feel neglected or insignificant.

3. Explain the reason: If something happens to you, you can tell him what it is, let him know your situation and know that you need some time to deal with it.

4. Apologize again: apologize to him again and let him know that you really regret not replying to his message in time. I hope he can forgive you.

5. Give compensation: You can propose some compensation measures, such as doing something he likes with him, or preparing him a small gift to make up for your mistakes.

In short, being honest with your boyfriend, expressing your feelings and reasons, trying to solve problems and make up for mistakes are important steps to maintain a healthy relationship.
