I can't say I would rather one or the other (divorced or not divorced). I do feel strongly about both parties having their divorces wrapped up in full before anything serious happens. IMO one life has to be totally "finished" before another one can start.

Divorce provides an awful lot of life experience and it's a type of experience a non divorced person really can't relate to. It's not a bad thing per say, just an observation.

I think once you reach your 30's most people have had some type of long term R so it's doubtful anybody is going in blind to the trials of a R.

Children also play a role (not a bad one but they do play an important role).

I'm not sure there is a correct amount of time to wait to date. If you mean dating as going to dinner or something casual I guess it's when you feel ready. Anything more though (for me) has to be after a divorce is final.
