I'd approach her and ask her about it. The best way is to just be upfront and find out what's going on. That's the best because it could help avoid a lot of heart ache. That's why I'm always honest with people about things, especially people I fancy.
Sorry, buddy. I've been there and it sure isn't any fun. I wish you luck.
You're my Honeybunch, Sugarplum
Pumpy-umpy-umpkin, You're my Sweetie Pie
You're my Cuppycake, Gumdrop
Snoogums-Boogums, You're the Apple of my Eye
And I love you so and I want you to know
That I'll always be right here
And I love to sing sweet songs to you
Because you are so dear
