I can't really help you out right now, YT is blocked. But look at it this way, if you REALLY want to sing that to a girl, you'll at least try learning the chords. I believe in you, and you should too man. NOW GO LEARN SOMETHING. You'll be that much better at guitar. And if you're all like, "I learned this just to sing to you, mahlove." She'll love that shht. Trust me, it's the thought that counts, she'll feel the love if she knows it there.
