Should me and my bf breakup?

Me and my bf have been dating only 4 months and i believe his gonna start being abusive. Im 16 and hes 15. Hes really controlling. If i go to a party i need to tell him wat i did there and who i talked to. And if i don't tell him im going he will get really mad. I cant post any pics that he doesn't like on fb. I cant have any boys on my fb. And he needs to have my email and pword. And every time we get in a little fight he trys to kill himself. What should i do.?
