It is not appropriate for your fiancé to go through your dresser, closet, or dirty laundry without your consent, especially when you are not present. This behavior is a breach of trust and privacy and can be seen as a violation of your personal boundaries.
Respecting each other's privacy is an essential aspect of a healthy and trusting relationship. Everyone has the right to their personal space and belongings, and going through someone else's personal items without permission can cause feelings of discomfort, insecurity, and violation.
Open communication is crucial in any relationship. It's important to express your feelings and concerns about this behavior to your fiancé. Let him know that you feel uncomfortable with him going through your personal belongings without asking. A healthy relationship involves mutual respect for each other's boundaries, and he should understand and respect your need for privacy.
If he insists on continuing this behavior despite your concerns, it might be helpful to seek the guidance of a couples therapist or counselor. A professional can facilitate discussions and help both of you work through any underlying issues that might be contributing to this behavior.
Remember, setting boundaries and respecting each other's privacy are fundamental aspects of a strong and loving partnership. If your fiancé truly cares about you and the relationship, he should be willing to listen to your feelings and make an effort to change this intrusive behavior.
