Parents not liking my boyfriend?

So my boyfriend and I have been going out for 9 months, and my parents used to love him. I am 15 years old and he is 17 years old. About 2 months ago, my boyfriend and I got in a really big fight. I was crying and really upset and said a bunch of things to my parents that I shouldn't have. That night, we made up but my parents were a little iffy about him. They wouldn't let me see or talk to him, so we decided to run away a week later. That didn't exactly work out cause my parents called the police right when they found out and we went back home. Since then, my parents strongly disliked him and don't want me to be with him. They think he is too old, has anger problems, and doesn't treat me right. I disagree because he does treat me right and the only reason we fight is because I lie and **** up. I stopped now but my parents won't let me see him still. We do fight a lot, and my parents hear me cry sometimes in my room. I really care about him and I'm not gonna just give up on our relationship because of my parents. What should I do? And how do I make them like him again?(this is my boyfriends account his strait)
