Jada Pinket Smith and Will Smith have not hidden the fact that their marriage is an open one, even if in the past we were not sure what that meant for them. In a recent interview she clarified that it means "respecting that you're in a partnership, but knowing that you're an individual as well."
I am fine with that kind of an open relationship, and even polygamy as I said here. I am not an advocate, nor will I promote it, but I think the relationship with one's husband is something each woman has to make a personal decision about and not be influenced unnecessarily by those who aren't living it with them.
For me, open relationships are those in which you tell me when you begin to fall for someone else, and we can decide what to do about it. Will I give permission, probably not.
Some may say this opens the door to cheating, but I think it promotes honesty and communication first of all, and who says there's no cheating in relationships where the parties are all jealous and possessive?
I think that cheating cuts across both genders. However, in a relationship with friendship and mutual respect, I think it is easier to make cheating a non-issue.
