*hugs* Hon, if you keep holding onto the idea of getting back together with him, you'll drive yourself insane, and the hanging-on period will become a bigger regret than the breakup. Trust me on this. Let it go and choose to learn from the experience - you'll come out a stronger person for it.

I'm just going to fight to become someone I can actually be proud of, and to one day enter a relationship where neither of us will be settling for the other.
This is a good decision and a solid step forward. Roll with it.
