At first he was really sweet and we got along great. Now he calls me names all the time

Hello. Im Elizabeth and im 16 years old. I have currently been with my boyfriend for one year. At first he was really sweet and we got along great. Now he calls me names all the time everything from A to Z. He even yells at me for eating cereal or going to the store. I cant take it anymore. I dont really wanna break up with him because i really like him and he says he loves me. He homeschools and really doesnt have any friends unless they are on xbox. I would feel horrible to break up with him because then he wouldnt have anyone. He is extremely jealous and i cant talk to any other guy. He doesnt like for me to go anywhere eather. I dont know what too do. But i feel like i cant take much more. Help me
