Do any of your exes hold a special place in your memories or do you just go and try to forget them?

Do any of your exes hold a special place in your memories or do you just go and try to forget them?
I generally try to stay in good terms and remember my exes for the good things and not the bads.
Although there's one with whom I had a very brief relationship, not even an official one and that we ended in very good terms, and yet it makes me feel bad every time I think about it. I don't really understand why.
What about you?
