WANTS to date my spouse ? no problem
It seems to me that "true love" may appear between ANY PEOPLE.
And if my spouse can be happy with it, it would be a honor for me to offer her your dating.
In my humble opinion, this would facilitate a lot of issues. How many times I saw in the eyes of a maried girl that she would be VERY PLEASED to have me as boyfriend, without disturbances or her family life, without hiddings, fears, etc...
Same on the other side : your spouse has a nice brain etc, I would like to become his boyfriend.
The only thing that matters, is "respect the other one". Stay at your place of boyfriend/girlfriend, and do not break the family.
Remember that boyfriend/girlfriend is a "short term job" and that "family" means that we become old TOGETHER.
