I met my narc on holiday abroad in a place in a country I love. Its the one place on this earth I ever found peace and the thought of going back makes me sick.
I booked another holiday there in three months. I'm going to learn to love the place again as I did for decades before him. He's taken so much, I'll be damned if he can take that too.
I say go and reclaim it for yourself, re-write over the corrupted bytes on your hard drive, as it were. It may take a few tries but don't give up!
You've every right to be there and enjoying yourself and your friends. Should you see her, don't acknowledge - look right through her as though you've seen an unpleasant ghost. It will be hard but don't let the narc take another inch!
