I've experienced the same. My fiance split up with me (many years ago) and it was a hard time in my life. IMO, I'm totally over it now - I'm married with kids, house, dog... no regrets.

But every once in a while I have an "important" dream with him playing a major role. The type of dream that you think is trying to tell you something. I'm not sure what, unfortunately. Dunno how much help this is.
