Uninteresting

Hello. Hopefully my friend won't read this 'cause then I would be in some huge kick-@$$ trouble.
My BFF (name is to remain unsaid) likes this guy and I thought they were REALLY cute together- until I met him. Now I love him, and he's sweet and nice and hot and...yeah. We talked the whole time at my BFF's party, and I felt comfortable and...I think he felt comfortable, too. And sometimes, when we were talking (and I KNOW this sounds REALLY pathetic), we'd kind of brush hands or my hand would touch his leg ('cause we were in a car goin to the mall).
It felt great and all...but I feel guilty and I'm such a liar. I told her that it didn't mean anything (though I thought it did). Because she had a (so call it) crush on him first so I feel bad.
IDK what to do because I REALLY like him a LOT.
