Long Distance Relationship, Afraid To Lose Him

I really really love this guy because he's just so perfect for me.

I hardly get to like someone. Now since I love him I don't want to lose him.

We have just met once and that was for 3-4 minutes. It's a long distance relationship. We have known each other over the internet for a year now. But we dont get to talk much because he's busy with his business and family and friends.

He's really mature type and is 10 years older than me. He says he loves me and wants to marry me but of course we need to meet up and get to know each other but there's no way we can meet up.

I'm just afraid his parents may make him marry someone else by the time i get there. He says he cannot talk to his parents about me unless we meet and till we meet I'm just afraid of losing him.

What should i do?
