Trust is a fundamental aspect of any healthy relationship, and attempting to investigate or monitor your partner without their knowledge is a breach of that trust.
If you have concerns or suspicions about your relationship, the best course of action is open and honest communication with your spouse. Talking openly about your feelings, worries, and concerns can help both of you understand each other better and work through any issues together.
If you're experiencing difficulties in your relationship, consider seeking the help of a professional marriage counselor or therapist. A neutral third party can provide guidance and support in addressing any challenges and improving communication between you and your partner.
Remember, trust is the foundation of a strong relationship, and it's important to address issues in a respectful and constructive manner. Spying on someone is not a healthy or productive way to address relationship problems and can lead to more harm than good. Focus on building a healthy, trusting, and communicative partnership with your spouse instead.
