Should I fight to keep him or left him go?

Dahlia

I've been in a romantic relationship for 8 months.. I think we both give a good amount of effort in the relationship and trying communicate and understand situations etc.. but due to work situation he has to move to another city far away for 2 years and he thinks the idea of a long distance relationship unrealistic..

Should I try to fight for him to stay?

Or just let him go.. (how!!)

And how can I protect my feelings?
