Yes. He obviously 'fell in love' with you Katie97, and even when he said he could just remain friends, it was really his way of staying in your life with the hope that your feelings for him would grow, especially after he bought you the necklace. That's my hypothesis. None of his behavior is your fault at all by the way, and he's obviously taking the rejection in quite an extreme way. That happens with people sometimes unfortunately and it's due to insecurity and immaturity on various levels. He does need counseling and proper guidance and there's really nothing you can do for him now, so just keep a solid boundary of no contact, and it's kind of a blessing that you're both in different countries now, too. You're absolutely right Katie97, his behavior is unacceptable. Also, if what has happened really begins to trouble you then consider a little counseling as well, as it could help to bring you some peace of mind through this.
