Now that I broken up on then How do i move on?

I think everyone struggles with this questions. Most tend to jump into another relationship which becomes more disasterous than the last one. The only answer I've ever found is time, the pain will fade over time. If you wait long enough, you may just find the person that truely makes you happy deep inside. Keep yourself busy, don't let yourself be overwhelmed by depression, learn from mistakes and don't dwell on the past.
