Do I Have A Case Against My Abusive Boyfriend?

To preface this, I am 17 at the moment and he is about to be 23. Our relationship began when I was 14 and he was 19. We live in New Jersey.

So me and my “boyfriend” have been together for many years, it has been a sexually active relationship since the beginning. I consented everytime but I was a minor so it was statuatory rape. He lied to me about his age for the first year of the relationship, I thought he was 18. He has hit me multiple times, cheated on me, and over the past 3 years it has ruined me. I dropped out of high school because of anxiety, I was depressed and crying every single night because of him, I developed agoraphobia because every time I wanted to leave the house he would yell at me and threaten our relationship, which in turn left me housebound. I cannot leave my house by myself and therefore can’t hold a job or anything. I have record of all of the mental health issues, but I never told anyone what the cause was.

I have confessions from him via text admitting that he has hit me, i have one picture of a mark he left on the entire side of my ribcage. He’s broken my phone, held a gun to my head, and just so much more stuff. We have barely been talking as of lately, i’ve been distancing myself from him and the plan is to sue him when I turn 18. My parents still don’t know about any of this and I don’t want them to find out which is why I am waiting. They knew of our relationship and did not approve at first, but later was okay with it. He was very sweet in front of them and everyone else, but as soon as the doors closed he became a different person.
