(((hugs))) I'm feeling the exact same feelings.
I've vacated the premises and have been missing the old "him," what we once had together, and how we were first and foremost the very best of friends. But then I remind myself that the love of my life, THAT guy, is GONE. Has been for some time now, traveling further and further away. Not physically*, but mentally. He checked out, and I finally realized it's time for me to journey fourth, too.
So, I've been trying to turn the painful "missing" into healing "mourning".
EDIT: *I take that back, he left physically, in a way, too. It's just that an unfamiliar swollen, pathological liar stayed behind.
