which one hurts the most??

I was blog hopping on my off period, trying to find anything concerning our favorite couple,

when I ran into a translated tweet from Hwangbo on Miss Auditor's blog.

사랑하는거랑 이별하는거랑 둘중 뭐가 더 아플것같나여? 몇일전부터 계속 궁금해가지구...

I wonder what's on her mind and if she found the answer...

For myself, I remember how heart broken I was 

when my best friend broke up w/me after 4 years of being together.

It was tough for me then but now I wonder if it was much harder for him, 

being responsible for breaking the heart of someone you care about but no longer love.
