I should have left sooner

I very recently found out I was pregnant, I was very excited & I thought my boyfriend was too. I have been asking him more about his GED and getting a job in order, he’s been extremely agitated & after being asked several times to stop grabbing my vagina in public or when I’m getting changed (I’ve smacked his arm away from me several times for this), he’s yanked my hair, taken my glasses, my phone, hid my keys, shoved me, hit the pillow I’m laying on, drifted my car around a corner, walked to my work to jump in my car, refused to leave my work place, hurled a lot of insults at me & so many more things. He lives with my parents & I’ve called the police, so have they, as of 20 mins ago he’s pretended to shoot me, making comments like “I should just end you ni***”. I’m not going to say this is completely out of the normal for him because he’s gotten extremely handsy and held me down when upset before but I honestly felt like it wouldn’t have gotten as bad as it has. He makes threats that he will ALWAYS find me if I take his “kid away” & there’s an open case of DV assault against him that I have filed . I’m 18, trying to get things sorted out, especially for my child but I feel very very very stuck. I have money saved up, I am in the process of moving but I don’t know how to do this without him finding out where exactly I live, or trying to come with me. There are some of his belongings in my clothing and what not that I would really like to separate before leaving but don’t know how to do so inconspicuously.
