• Don’t ignore your intuition. Pay attention to changes in behavior and communication that feel off.
• Have an open and honest conversation expressing what you’ve noticed and how it makes you feel. Avoid accusations.
• Explain that your goal is to communicate openly and rebuild trust together.
• Request access to their devices and accounts to help address your concerns. Refusal may signal deception.
• Consider relationship counseling to facilitate transparency and reconnect emotionally.
• Consult with a divorce lawyer to understand your options if unable to reconcile.
• Prioritize your mental health with supportive friends/family, exercise, hobbies, etc.

Infidelity is always painful but beginning a dialogue is the first step to uncovering the truth.
