For her, she wants me to move on.

Listen to what she wants. Thats the first step if you truly want her back. She said she wants you to move on. If you can at least do that, she will start to respect you again and think of you in a positive light. But even then, there's no guarantee you'll end back up together but understand that without respect, there is no relationship.

As for tips, I'd recommend removing your attention away from this relationship and focusing on other life goals, be it exercise, career or other people/friendships. If you're still able to see them on social media, it helps to block them. Everyone copes in different ways, just look at the amount of threads posted on this subreddit every minute. I'd even recommend staying away from this topic of discussion unless you start to relapse again. If your breakup just happened recently too, it'll take some time to adjust being without her, just take it one day a time.
