Please help me get divorced!!!!!

I started this page a while back, and forgot about it, but now i am needing help with getting my divorce. We got married June 2012, lived together for 9 months, and the way he treated me caused me to unfortunatly take it out on my children, and i have gotten help with that. We have tried several times to make it work, but not anymore. He is emotionally abusive. He does not see himself as abusive because he does not hit me. But he constantly belittles me, tells me to be a certain way, act a certain way ect. And he takes atvantage of me being in his car, using it as a control space, where he can rant and rave at me, and i cant do anything about it. 2 weeks ago, on Oct. 6th,2016 was the breaking point. He took me to town, and decided to be vindictive. I told him to just take me home, and on the way home he constatly ranted and raved. When we got to my house, he WOULD NOT LET ME OUT OF THE CAR!!!!!! His car has the driver lock when the car is running, and he kept claiming "nobody else has problems unlocking the door" I ended up haveing a massive panic/anxiety attack, and he finally let me out. I have not spoke to him since. I really need help with the divorce, to file and to serve him with the papers. I appreciate any help. Thank you.
