There could be several reasons why your boyfriend acts this way and doesn't allow you to see or touch his phone while freely accessing yours:
Privacy concerns: He might value his privacy and consider his phone to be a personal space that he doesn't want others, even someone he's close to, to access. This could be due to various reasons, such as personal messages, photos, or sensitive information that he prefers to keep private.
Trust issues: It's possible that he has trust issues, either related to your behavior or past experiences in previous relationships. If he is possessive about his phone, it might be a sign of insecurity or fear of you discovering something he doesn't want you to know.
Communication style: People have different communication styles and boundaries. It's essential to discuss this with your boyfriend to understand his perspective and see if you can find a middle ground that makes both of you comfortable.
Unequal expectations: Sometimes, individuals might unconsciously hold their partners to different standards. He may feel entitled to check your phone while expecting his own to remain off-limits. This imbalance in expectations should be addressed in a healthy relationship.
Past experiences: Past experiences or traumatic events could influence his behavior and reluctance to share his phone. It's essential to be empathetic and open in communication to understand the underlying reasons.
Personal issues: There could be personal issues he's dealing with that make him unwilling to share his phone. This might have nothing to do with you directly, but he might need some time and space to resolve those issues.
Regardless of the reason, the key here is open communication and trust. It's important to have a conversation with your boyfriend about how you feel and express your concerns. Let him know that you value trust and openness in the relationship and that you'd like to understand his perspective better. Encourage him to share his feelings and reasons behind his actions. Mutual understanding and trust are vital for a healthy and fulfilling relationship.
