What should I do about my oversized boyfriend?

So...me and a guy have been going out for almost 3 years...yeah i know....im 20, and hes 24.....well latley, well the past year or so, weve been having all sorts of problems, arguments and stuff, and yes theres been violence kinda. Hes a pretty big guy too. Hes like 6'5'' 280 pounds mostly muscle, hes a really buff guy. Im just 5'4'' 115 pounds. The only thing hes done though is push me against a wall and put his hands around my neck. But thats about it, but its been getting worse... i love him....should i continue to be with him......why or why not??
