Answer:
You have to show him you really want him back. If you really like him, you have to fight for him. (not literally. that'll put you in Subject: Psycho at the Insane Asylum) You have to show him you care and that whatever happened to make him want to leave you shouldn't keep you two apart. And if you do take my advice, show him that you wanted him back so bad you resorted to Brainly. And make sure to tell him to say thank you to me for giving him the love of his life back cause im sure you're a good one since you care so much! GO GET HIM, TIGER
