My ex-girlfriend who hasn't contacted for a long time suddenly sent a text message asking why she deleted her WeChat. How should I reply to her?

Examples are as follows: Dear, I'm sorry that our relationship has broken down, but I miss everything with you very much. I used to regard you as the only one for me. I really loved you at that time, and I was willing to give everything for you. However, because I broke up with you, my heart was very painful. Deleting wechat may make me forget you completely. I've been in pain for a long time and I can't get out. Thank you for asking me this question. Give me one. It takes a lot of brains to remember, old iron. Let's adopt it.
