Don’t have the conversation inside the home. Have the conversation while you are leaning against your car. Tell her calmly, "Dear, sometimes men and women have different ideas about the meaning of fidelity. So, if you will not dive with me, that is one issue, I can respect that, but you telling me what I can do or cannot do is stepping beyond the boundaries of what I would call a faithful marriage. Let flip the shoe around to the other foot and see how this sounds. How does this sound, ’You know, so and so’s husband doesn’t let her go outside with her friends because he thinks that her place is in the home.’ Then ask her, ’Just how does that sound to you? Now, replay what you have said to me about what I can or cannot do and listen with your own ears to how that sounds?’" Give her a pause. Then, ask her what the date is and when she replies lookdown at your watch and tell her what time it is. Next, calmly ask her what she needs from the store and tell her that you are going shopping and will be right back. Diving is irrelevant. Mate, - if this were on the other foot and you were tell her what she can and cannot do and were keeping her locked up in the house your neighbors in a lot of states would file charges on you on her behalf. The diving is irrelevant, one person in a relationship who is telling the other person what they can and cannot do is abusive. It is time to claim your half of the relationship or set sail. Good luck.
