My dad doesn't want me around this guy...He doesn't know him.And I like him. A lot. HELP PLEASE?

My aunt live an hour away in a development of these really nice big houses lol and his family is pretty rich. Mine and my aunts is as well.It was new years, and my parents met his parents, but he wasn;t there. And my dad got to know them, and a few weeks ago, I was at my cousins house. He spotted me. The day after I left, my cousins are friends with his little sister so they were at their house. They were in the bathroom, lol and the guy(the one i like <3) comes in while they were expirimenting with makeup, and take the 2 of my cousins in to another room, and asks them for my name, number, and then he texted me. He said he wants to hang out next time I'm there. We're both 15. I said I'd let him know when Im there. I saw my cousins when they came to my house, and they told me that he said he missed me <3 He's never been serious about any relationships, but now he is. And I like him. My dad doesn't want me to have anything to do with him. He hasn;t even MET him. He's basing his judgment on him off of his parents, who my dad says are losers. I want to see him so badly...and my dad is ruthless, I could beg and plead and he wouldn't even consider it. Please help me. Thanks
