<human>: Condense the text into a few key points

So today has been a pretty great day for me. I'm 17, male. A few months ago, I weighed 250 pounds. Now, I'm 156 pounds. I've cut my hair, styled it, and starting to gain more confidence. Today, a friend comes up to me and tells me he asked a girl I liked what she thought of me, and if she would go out with me. She apparently said I'm handsome and ''would go out with me if I asked her'' apparently in a ''girly'' (by this I mean she said that in a girly way) way. I'm wondering what this really means? Does she actually want to go out with me? If she does, how do I ask her out? I'm kind of a shy guy, and this would be my first time asking a girl out, ever. What do I say? How do I approach her? Help me out here :I I should add that this girl is my friend, but we don't talk much at all outside of class.
Thanks

Duration of relationship: I've known her as a classmate/small time friend for 2 years. Romantically, 0 minutes, 0 seconds.
<bot>: Girl apparently I like said she would go out with me if I offered to take her out. I don't know how to ask someone out.
