Okay is this true love, or is this really just being a great friend? PLEASE HELP! It's tearing me apart.?

As cliche as it is, you just need to follow your heart, and by the looks of it, it's leading you to her. Go for it and if she rejects just keep trying and tell her that you love her and that you will never hurt her. If all else fails watch the movie Moulin Rouge with her and she will be crying in your arms swearing that she loves you that way too! Good luck!
