I want to get back together with my ex. He asked me who I was, and how to answer it so that he didn't know who I was and wouldn't delete me. I'm afraid to face him, afraid that he will delete me.

I think if you have such an idea, you should meet him and have a good talk. Let's see what he means. It would be easy if he didn't forget his old feelings. If he wants to think about it, you can say that being an ordinary friend first and dating first will not affect his consideration. In this way, you will have more opportunities to contact him, and the greater the hope of getting back together with him.
