to me and i know not to many.... my thoughts are a separation... is just that. its time to figure out how to be individual again and work in all the quirks for both your futures.. figure out what is best..

to me going to a reunion with her is not doing this.. it is leaving the option open... giving her hopes that it may work out.. its not letting go .

now if neither are ready to let go why is there even a separation?
would that not be still a couple and working on issues? a separation is not needed for that..

I guess it depends on the type of relationship yall still have? If there is tension or either of you is seeing someone else, then I would say it wouldn't be wise to go with her. Also, is she wanting to appear that everything is fine and dandy and yall are still together? Or does she just want you to go so she doesn't have to go alone? Either way it seems kinda awkward considering the circumstances? But if yall are still good friends then who knows?

Well your only separated depends on what kind of a relationship you still have .Go as friends and introduce yourselves that way .
