I have been dumped by both kinds of people (and I'm sure there are those of both kinds that feel I dumped them) and the only things I have learned is that it hurts to be dumped or to be left, whatever but we all are moving at different rates and, as Tears for Fears put it:

It's my own design
It's my own remorse
Help me to decide
Help me make the most
Of freedom and of pleasure
Nothing ever lasts forever
Everybody wants to rule the world
