@MrMekzy_@oku_yungx I can't determine what kind of person he is, only you know him better than anyone else, based on the time he has spent living with you. With that understanding, you'll be able to decide what to do next.
@MrMekzy_@oku_yungx First, your feelings are completely valid. He crossed a boundary by entering your house without informing you or obtaining your permission. The good thing is that he admitted to it. But, you may want to address the situation firmly to express your disapproval of his actions.
