Problem with my videogames and my friend?

My friend and I were planning to hang out when I got back from my cousin's house a few hours away. He wanted to hang out at his house and I wanted to hang out at mine, and we got into this thing where he said i disrespected his house or whatever, I really don't care. The thing is he had been borrowing two of my video games from before because he had just gotten a 360. When I went away i let him borrow another one of my games, then he got mad at me. So he has three of my games and won't give them back. What should I do? I can't really find out when he'll be out so I can go to his house and ask one of his family to give them back, and I don't really want to drag my parents into this.
