I need support

I’m 17 and my friends brother is 19, he’s been extremely touchy with me and it’s usually while i’m under the influence. I talked to him once after it happened the first time and he apologized, then after it happened a couple more times to my friend and I we confronted my friend and told her to talk to him and she said she did and he apologized.

I was over at my friends house the 14th and he started throwing food at me and saying I was the only one he did that to. The next day I left and I went home, I planned on staying away from my friend for a while but then the 16th my friend and her brother showed up at my house without telling me they were going to and I broke down because my house is my safe space.

I plan on going back when I get back into town and having a conversation with him telling him that ‘I don’t want him to touch me at all and it makes me uncomfortable when he does touch me, and it’s also really disrespectful since I have a boyfriend.’ I’m just hurt and also scared..
