Me and my boyfriend broke up. Does getting back together actually happen?

This weekend me and my boyfriend broke up. Nothing went wrong, we both love each other so much and see a future with each other. He told me he won’t ask me to wait as it’s unfair, but he said he wants to better himself so he can put effort in to treat me how he wants to. Ultimately I’m a perfect world we would want to get back together. Does that ever actually happen? I’m sick over losing him and I’m struggling to work through it all.
