The breakup was initiated by my boyfriend. We didn't quarrel. We parted peacefully. We kept each other's contact information and sent him back information. Does he remember?

Make sure your heart first: Do you still like him?

If you like it, you can find him again, sum up the reasons for breaking up, and then remember never to humbly ask him to get back together and not to threaten him. You can go to him with your summarized reasons and let him talk about the reasons why you broke up.

If you don't like him, there is no need to contact him. Don't show a little nostalgia for him. Make him wonder how you can live so well without him. Only by living well can we keep him in a sense. Men don't pity poor women, but admire independent and capable women.
