In all my years of schooling, the first time I remember hearing a teacher bring up their spouse was in college. Before that, zero mention. You could infer it, from the fact that some of them were "Mrs" rather than "Ms", or because they got pregnant, but that's about it. None of them ever felt the need to let me know that they were married. Because I was their student, not their friend. The classroom is not the place to bring up your personal life for any reason.
