You're divorced, I don't think there's really a time limit on that one, stuff like that will tend to pop up occassionaly. Bad stuff, especially when it involves people you know, likes to creep into the head, and dreams tend to mish-mashes of the abstract and real. You think you've dealt with something, and you may well have, but every so often it will show up again to kick you in the teeth. The natural remedy for most things like this is to watch a comedy and have a drink or two, as opposed to dwell on it. If you dwell on it then you'll just think you solved it, and a few months later get upset when it pops back out from the mental closet.
