I deeply hurt my ex-girlfriend. I want it back. What kind of text messages should I send?

I have you in my heart.

What you need to do is tell her what you did wrong before, love her, hope she can forgive you, give me a chance, say it is necessary, but more importantly, tell her by actions that you want to be with her and will never give up on her in the future. ...

To be honest.

You just finished high school and then went to college. You're not in the same school, so you're sure to find someone separately.
