Yuck, even when you've "moved" on it still sucks to have to confront your past loves. Last time I seen the person I was with for 3 yrs before LK and I got back together it made me feel all weird inside. Trying to relate to this person as an aquaintense rather than the way we'd been was very, very strange. I was glad to hear he'd moved putt state. Even tho I was happily married with 2 amazing kids, still made me wonder if he thought something like thank god, missed a bullet with that one or such.
I'm sure your life is really good without them. Relationships end for a reason
