Can I press charges on my dad from when I was 17

Long story short I’m 18 now and my dad has always been an alcoholic. When I was 17, which was last october this happened.. one night my dad got super drunk at his place with friends. I didnt know he was drunk, because I had just gotten home from work and he told me that he wasn’t drinking anymore.. so I go up to him, tell him goodnight, hugged him and as I tried to walk away he puts his arm over my shoulder and grabs my breast in front of everyone . I was shocked and I ran off. He chased me, pulled my hair, pushed me, tried to push me again, and called me names. I left the house and moved in with My boyfriend. The case is still open and it’s January now. I haven’t talked to him since Christmas. I went over there to see my step siblings bc I felt I should have . I felt extremely uncomfortable. He doesn’t remember doing it. On other occasions when he was drunk he would do weird stuff too. Example, one night when I was 14 I had just gotten out of the shower. I had nothing but a towel on, and he came up behind me and hugged me tight and tried to drag me I think, I told him to get off me and he did. I honestly didn’t think anything of it then besides him just wanting a hug. But now I think it’s wrong and messed up. When I was younger we would “wrestle” and every time he would “accidentally pull my pants halfway off. Again, didn’t think anyone of it because i was like 7 and we were wrestling I guess. I’m not sure why but after all of that I still wanted him in my life because I denied he would ever do somethinf like that do me. When he’s sober he has never done anything weird like that before. Only when he would be drunk, and he wouldn’t remember it. But I would and I still do. In high school I used to have in the back of my mind that he was odd with me and I would have a panic attack and start crying etc. I felt like i couldn’t tell anyone because my dad is well known wealthy person in my city who buys everyone’s friendship and everyone likes him for that I guess. I’m so lost.
