Can you date someone who is married or is it adultery and not dating?

Dating someone who is married is generally considered adultery, as it involves engaging in a romantic relationship with a person who is already in a committed partnership. This not only breaches the trust and commitment in the existing marriage but can also lead to emotional and legal complications. Most ethical frameworks and societal norms discourage such relationships, viewing them as harmful to all parties involved. Ultimately, it's important to respect the boundaries of committed relationships.
