Answer:
Now, as i can see this is obviously to do with a boy, and you two must be in a relationship. But before i start dating someone i make sure i can trust them otherwise if you are in a relationship with someone and you cant trust them, you don't know what that will lead too. Just prove to him that he can trust you, and you will both build up to be able to trust eachother, but remember to take your time, as trust does take ages to build but remember seconds to shatter.
