Thank you very much, and I agree completely about the stability of our relationship.  There's no doubt that open relationships can be very destructive.  That's just the way it goes.  If anyone is even the slightest bit insecure about their relationship, or both parties aren't 100% sure having an open relationship is a good idea, they shouldn't do it.  I got lucky, no doubt.  But I know far to many relationships that crumbled within weeks of being open.
