In Texas, you can file for divorce on the grounds of adultery. However, the court may ask for proof. If you are unsure that your spouse is cheating on you, it may help to take a step back and assess the situation. After all, every situation is different, so what you think might point to infidelity may be something else entirely.
You do not want to make accusations unless you have some proof. However, having suspicions of cheating on its own indicates that your marriage is not doing the best, so even if you find out the issue is not that your spouse is cheating, doing some investigation into the situation could help you reveal other weaknesses in your marriage.
In general, Psychology Today states that if you have a gut feeling that your spouse is cheating, then it is usually right. You still want to do some investigation and look at the situation with fresh eyes before you confront your spouse. This will help you to avoid a bad situation if you are wrong.
While no two people will act exactly the same when they cheat on a partner, there are some signs that are pretty common. If your spouse seems very agitated or upset when you bring up the topic of adultery, this could be an indicator of a guilty mind.
Watch for him or her improving how he or she looks, especially when going away from home. Look out for secretive behavior and hiding things from you. Unusual schedule changes are another common indicator of infidelity.
Finding out your spouse is cheating can be devastating, but it is better to find out sooner than later. You do not want to stay in a relationship where your partner does not respect and value you. Again, if you discover he or she is not cheating, then you may also learn that your marriage has trust issues that you will need to work on if you want to avoid a divorce.
