Honestly....you're way too young to be dealing with that crap. Love is an action, yelling and screaming is not loving. You may feel like its love because you started dating when you were 16 but seriously, it sounds like you two are just wrong for each other. Get out now before you look back and its been 10 years and you can't leave. It may sound harsh but I've been there and thought it was love and it wasn't. It was 2 people, too insecure to be alone, fighting constantly. Learn how to love yourself first, only then can you truly love someone else.
