Do be careful if you start dating. My personal rule of thumb has always been to give myself 2 months for every year. It has helped me gain clarity for myself.
I have heard of folks coming back from the brink. Every sitch and circumstance is different. In the cases I'm most closely associated with (not from this bb) it was a witnessing of changes and the realization of what would be lost in oneself to not look further and explore reconciliation.
