I believe the correct word is:
Awwwwwwwwwwwwwwe
How sweet, I have actually been in this situation, and ended up dating both girls as they dated each other for about 6 months. Eventually one of them met someone else, but it was a great time.
Three-way relationships can work, and although I love FlamingNargles (H/G/L) I have more and more been drawn to H/Hr/L pairings lately, I find the similarity of the girls intelligence, and the opposing views of the world to be refreshing and gives Harry plenty of outlook and input.
Keep up the great work, I am loving it!
