I just found out something about my best friend?

I've known this guy for a year now, and I've started to fall for him for a little less than a year. Yesterday, a girl friend of mine started wondering if he and I liked each other, she thinks I don't like him but when she asked him... He told her that he's in love with me since he met me... SHe let me read the entire conversation.

I can't believe he loves me!! But here's the problem: I don't know how to talk with him anymore because I'm afraid I'll say something that will make him fall out of love with me! And my girl friend told him to tell me that he's in love with me, but he kept repeating he's afraid to because he doesn't know how I'll react...

I really want him to tell me everything himself because I love him too and for the past year he's been the only person who understands me perfectly, knows how to make me laugh until it hurts, and knows how to make me feel better when I'm deppressed...

Many people say he's my soulmate, and I think that's true too :)

I love him a lot, he's the only one I've pictured being my husband and the father of my children <3

what can I do now??
