Yes, in Texas, adultery is considered a ground for divorce. If your spouse has cheated on you, it can be grounds for ending the marriage. Texas allows for both fault-based and no-fault divorces, so you have the option to cite adultery as the reason for the divorce if you choose to do so. However, it's important to consider all aspects of your situation and consult with a family law attorney who can provide guidance tailored to your specific circumstances. They can advise you on how best to proceed with your divorce and help protect your interests throughout the process.
