HELP! Parent & boyfriend crisis

Guys, I'm freaking out. I met this guy almost a year ago. We've been dating for 6 months and I've never been happier. I'm hopelessly in love. And the great thing is, so is he. Our love feels equal, like one is not greater than the other. And I've never felt that way. But here's the problem; I think he's my soul mate. I'm 18 and hes 30. Yea yea yea, I get judgement all the time. My parents aren't okay with us dating for 1 more year. But I'm so in love. I've never met someone to make me feel like this and I've been in love before. I think about marriage and kids with this man. I love him to death. I think he's the one. It's soon to say that, but when you know, you KNOW. My parents want us to wait another year so they can feel more comfortable, but how can I say goodbye to my soul mate?? A day without him being mine is a day I don't ever want to see. Help! I don't want to disrespect my parents and not lie but I love him. It would kill me to end something so good. Something that comes once in a lifetime.
