My Cousin Is Trying To Sue Me

Me and my younger cousin (he is 23, I am 28) went on a trip to Europe last month after him asking me to go for a long time. My cousin is a pretty strange dude who has few if any friends and has been in trouble multiple times for inappropriate behavior in high school and several jobs he had after graduating. He is basically a lazy and pretty dumb dude that cannot keep a job and actually has a history of posting weird questionable things online (including him being sextorted, pictures of drugs and alcohol and occasionally racist/sexist memes.)

He went about two years of not getting in trouble, so I figured he must be doing better lately. Anyway one day he calls me and asks me on a short trip to Europe for April 2024. He asked that I pay him $1000 altogether, this included our plane tickets and hotel, which was cheaper than I expected. He just wanted me to cover a few dinners and some extra things we do and we’d just call it even. By the time we left for the trip, I had already paid him 600 out of the 1000 he asked for.

Anyway, the trip was okay for the most part. However, on our final night before going back home, he was highly intoxicated after drinking all day and got angry at me for telling him to stop drinking, because I knew he would be sick/hungover the next morning and would make it difficult for us to travel back home. He had an absolute freakout claiming I was telling him what to do/ruining his trip and calls his mom for some reason. She tried to calm him down, which made him more upset. He starts screaming in our hotel room that everyone is against him and begins throwing things and punching the walls.

After about 40 mins of this, I get angry and yell at him to stop and calm down. He called me the N-word (I’m not even joking) and threw something at me. I body slammed him and punched him in the head 5-6 times before he tapped out. He cried, ran downstairs to tell the hotel manager and tried to have me arrested. When the manager said he wouldn’t call the cops because my cousin was obviously wasted and didn’t have a scratch on him, ( I didn’t hit him in the face, so there were no marks)

He packs his stuff and rushes out against my and the managers wishes. Upon returning home, I got a confidential letter in the mail saying he was going to sue me for $1000. The small claims letter said I paid him less than I actually did, and he wants me to pay $400 that I don’t owe him, on top of a hotel he got for like 2-3 hours literally right before going to the airport. The hotel cost $300, he was there for like 3 hours and he wants me to pay for it along with a few hundred extra dollars for no reason. I have screenshots of every payment I sent him.

Our online court case is in august. Do you think I’ll have to pay him $1000? I don’t think he has any evidence of the extra money he’s claiming I owe him, he is just angry that he didn’t get his way. What do you think will happen? I only owe this loser $300-400 rn, he wants more than double that and I don’t think he has any proof
