My wife and I have been married for about four years. We grew up in the same religion, went to the same university, and have many things in common. But in the years since we first met, I find myself changing rapidly. I have lost all interest in participating actively in our religion. I have also decided I don’t want kids (even though we always assumed we’d have them). My wife is an incredibly patient and understanding woman. She has said nothing to indicate that she is upset with me about these sorts of things. But I can’t help but wonder: Do I owe her an obligation to stay the same person that she married? I mean, if she married me under the assumption that our lives would go on a certain trajectory, and I suddenly (and unpredictably) alter that, am I betraying my vows to her? Do I need to stay the person that I was seemingly destined to become?
