I think Katherine Hepburn once said something to the effect that men and women should live next door to each other and just visit every once in awhile.

Questions about relationships are what makes us human. My former husband and I had some very great times and therefore a lot of important things were overlooked.Had they been worked on, maybe we would still be together, then again, maybe we would have seperated much earlier. If something seems fundamentally wrong to you and him/her and quite strong feelings about it remain for sometime, best to work on it right then. Warning! Be prepared to accept/live with the consequences.

If I am ever blessed with another SO, I'll have a much different perspective and he will have to be strong within himself to accept my personality. And vice versa.
