This is an old thread, so not sure if the OP will respond.

But pay attention to this detail:

"...We were long distance for part/most of it. I was dumped...This month, we happened to be in the same country and saw each other..."
It is a fair guess to say that the LDR aspect contributed to the break-up.

It is also fair to say that exes from LDRs might have a better chance than usual of a reconciliation where the the distance aspect is removed, if that was the major cause of the break-up.
