There could be several reasons why your boyfriend is unwilling to let you see, touch, or access his phone while freely taking yours:
Privacy Boundaries: People have different levels of comfort when it comes to privacy. Your boyfriend might be someone who values his privacy and considers his phone to be a personal space. He may not feel comfortable sharing it with others, even if he has nothing to hide.
Past Experiences: It's possible that your boyfriend had negative experiences in the past related to privacy invasion or trust issues. As a result, he might be more guarded about his phone to protect himself from potential harm.
Insecurity or Jealousy: Your boyfriend might be feeling insecure or jealous, and not letting you access his phone could be his way of preventing any misunderstandings or conflicts that may arise from your interactions with his personal messages or contacts.
Unresolved Issues: If there are underlying issues in your relationship, such as trust problems or unresolved conflicts, he might be using his phone as a way to maintain some control or distance.
Different Perspectives: People can have different attitudes towards technology and personal devices. For him, the phone may represent an intimate space that he's not ready to share, while for you, it might be a more casual thing.
Lack of Reciprocity: If he is unwilling to share his phone while expecting you to share yours, it could indicate an imbalance in the relationship, where he might not be treating you with the same level of trust and respect that he expects from you.
It's important to have open and honest communication with your boyfriend about this issue. Try to have a calm and non-confrontational conversation, expressing your feelings and concerns without accusing or blaming him. Respect his boundaries while also expressing your desire for more openness and reciprocity in the relationship. Understanding each other's perspectives and finding a middle ground that makes both of you comfortable is crucial for a healthy and trusting relationship.
