Healing after cheating?

How do I fully get over heartbreak? Thought I was with the love of my life and started to plan a future together until he cheated and asked for a break. I just wish to fully heal from this and not be tempted to go back to that toxic relationship if the opportunity arises. I know people say move on to another guy, but I couldn't do that to anyone because I wouldn't be 100% committed. I know I need to be by myself, but what are some ways that I can heal and self-improve so that I can know my worth in the future and what I want out of life.

Any advice or stories from what you girls have done would help greatly xoxo
