Not sure how to proceed or just move on?

You are not going to convince her overnight. It will take time and consistent action. You actually have to get on with your life without her and reach a point where you don't need her to come back. That is the detachment you need to reach.

So, keep DBing. Stop worrying about how she will react to your communication or lack thereof. Focus on yourself. How can you improve yourself? GAL as much as you can. This is a long process and you are still at the beginning. You slipped up, but that just means you learned what not to do next time.
