No, I don't think it helps. I moved 500 miles south and he moved 500 miles north. It didn't help. The only thing that helped was that I had to move in with family and I couldn't sit in a dark, empty apartment by myself watching movies and eating chips.
It's been over a year and I still cry over him at l
east once a month.
Bad memories are going to be triggered by anything. If it's not physical landmarks, it's smells, sounds, feelings, words, pictures, etc.
