My ex-boyfriend suddenly sent me this text message. What does this mean?

Maybe he just wants to give a reasonable end to his previous relationship. He feels guilty and refuses to let go, so that he can comfort his heart by telling you.

After breaking up, you may not be used to a person's life, and you will often think of your time together, further stimulating his inner feelings. There are many things you misunderstood him, and he didn't have time to explain them. I want to make up for these regrets through this passage.

On the surface, I want to have my own life, but I want to make up with you, and I will regain the opportunity to associate with you through this confession.

You can choose the above three possibilities according to the actual situation.
