Reissue the question: What should I do in the face of the anonymous ambiguous message sent by my ex-boyfriend?

I think it's nothing, really nothing. He just cares about you like a friend. It's just that he sent it to you on someone else's mobile phone, because he was afraid that you would miss him like this, that you would miss him again, and that you would be sad. He doesn't want you to feel sad when you think of him, because he broke up with you. I think he only thinks of you now, so he cares about you. Breaking up doesn't necessarily mean that you don't have to contact or meet. After breaking up, you just went back to the time when you were not lovers before. Don't think about it, tell him that you know he sent it, and let him send it directly in the future, and then make friends with him. Forget it. The past is the past. Dress yourself and face tomorrow. Hey hey! I will also send it to people I used to like. I wonder if she will think like you.
