I really need advice 😔

My ex boyfriend recently broke up with me. We dated for three years. I used to give him a bunch of blowjobs. About six times he forced me to. I told him I didn’t want to and he would pull it out and push my head down on to it. Sometimes I couldn’t lift my head up because he’s so strong. He would always try to touch me and lift his hand up my shirt. I would grab his hand and he would push my hand away. I had to use a lot of force to push him back. It took all I had to. He would grab me and get really mad and like shake my arm with anger. I’m 16 and I didn’t realize how wrong this was until we broke up. I don’t want him doing this to other people. What should I do? Could he get in trouble for this?
