What are some dating tips for married men & women?

I would think that if you go through all that work to become married, it would be exponentially simpler to date the person you chose to marry. Also, I thought one of the perks of marriage is that you don't have to deal with the speculative nature of dating as a single. I realize there are such things as open marriages, as well as polyamory (sp?) relationship....but I'd guess that those may not be as easily navigated as one might think. Emotions ultimately can't be kept out of the human equation, and if not managed or addressed - will just entangle any interaction. p.s. The 'being a very good fan of one man, one wife' concept seems conflicted here. Sounds like an opportunity to explore what one really wants from a relationship.
