Really scared to go to his house after a fight?

Okay. This might be long but I'm not sure. I like my friends brother and a little over a month ago we basically went out for a weekend. In that weeks we kissed. Last night he texted me and was like "WTF quite telling people we kissed it didn't mean anything... Get a life and stop tellin people we did..." so I was like "who did I tell" and he wouldn't tell me. Then for about an hour we were fighting and he was saying things like I'm ugly, I can't get no boys, how I look creepy and look like I'm gonna rape someone and I stink. He also was trying to convince me we dint even kiss! Anyway I'm going to stat at his house for a week while my friends are out of town (not for him but his sister cause like I said we're friends) I'm just scared to see him because I'm going over there soon. It's going to be really awkward. Btw I'm 14 he's 13
