When it comes to trust, I have always preached that I believe that trust is a choice. In other words, you have control of who to trust as opposed to just equally choosing to trust or not trust someone. At the same time, you also have the choice in which you want to keep your own privacy. It is your right to keep something private if that is what feels most comfortable to you.
Within any relationship, the goal is to form a bond where two people feel they can trust each other while also respecting each other’s privacy when asked for it. It is a form of manipulation if someone guilt trips you into telling them something or doing something out of your comfort zone by saying that you should automatically trust them. It can take some time for someone to be able to trust so it is important to respect that and to have patience. No one should take this too personally because trust is something to be earned. It is okay to inquire about the other person’s reasoning if you are concerned about there being a lack of trust but the best thing to do is to be both receptive accepting of their response as opposed to being reactive, upset, angry, and/or disappointed. A negative response can result in resentment along with more reason to be distrustful.
Also keep in mind that if you are in a situation where you feel the need to overstep boundaries and betray the person’s trust such as going into the other person’s email, text messages, social media, etc. then that means you have very little trust in this person and it might be a good time to reconsider keeping this person in your life. On the other hand, maybe this is a time to dig deep from within to see what would provoke you to do this. Did someone betray your trust in the past? Do you have a problem building trust in general? If it stems from an insecurity or paranoia on your part where the other person did not do anything wrong or signal that something was wrong, then this is something that you might need to work on. I think going behind someone’s back to look through their stuff is a betrayal of trust and it can be expected that any trust that was in place could be at risk of totally being broken and could also create a wall between you and this person. It is understandable to be curious or to question a person’s intentions from time to time but it is much better to approach a person with your trust concerns than going ahead and investigating on your own and betraying someone’s trust in order to provide you security or to confirm any suspicions you might have. Remember that with trust, it is both give and take. In order to receive trust, you must be able to give the other person your trust in return while also taking the right actions to prove that you are a trustworthy individual to begin with.
