How secure is your marriage? Is he the jealous type? How much do you want it? Most guys wouldn't be able to handle it unless they feel really secure in the relationship. If I was in his shoes, and I loved you, I'd want you to be happy, and I would be open to it. (I've been in this situation before with a girlfriend, and I gave her the green light, but she never pursued it.) I always figure if someone is with me it's because they want to be, and if someone can come along and take them away, then I must not have had much of a hold on her in the first place. I think it's all down to whether he feels secure enough.
