Save the ex-boyfriend a word and talk about the mood.

Paragraph 1: I want to call him, but I hesitate.

There has always been a knot in my heart, and thinking of you is always accompanied by pain and regret. Now I miss you again, I want to call you, but I am hesitant. I'm worried that you will reject me and that you don't love me anymore. However, when I think of the good times we spent together in the past, my heart is full of longing and expectation. I don't know what to do. All I know is that I love you and I want you back.

The second paragraph: I feel really bad.

The moment I lost you, I knew it was a mistake I made. I'm really sad because I didn't cherish and maintain our feelings. You are my first love, and I always thought we could go to the end together. But now, I let you out of my life. I really don't know what to do. I just want to make every effort to get your love back.

The third paragraph: I will change and let you see my growth.

When we broke up, I knew I was too immature and naive. But now, I have learned to mature and grow. I know I still have a lot to change, but I have already started to change. I believe I am ready to be a better person and a better partner. If you can still see me and see my growth and change, please give me a chance to save your heart.
