Warn friends and family:
He will at some point reach out to your friends and family, and he will seem like the sweetest, most sound-minded man. He will ask them how you’re doing. He will tell them how much he enjoyed getting to know them. He will write an indirect love letter to you, telling them how much he loved you and asking if there is anything they can do to help him get in contact with you. Warn all of your friends and family ahead of time that this type of message might be coming their way, but that he has been acting completely insane and to ignore it.
