I would be honest about your feelings. In addition, ask her out on a date. A real date or better yet meet her out and flirt with her, pick up on her and pay attention to her like you had just met her and were trying to get together with her. Even get adventurous with hooking up later. Maybe have a fantasy of hers waiting when you get home.
Basically make the entire thing about her. Everyone wants attention. I am definitely and an expert or have great advice like many in the forums. This is just my opinion. Trust me bro, I had a great lady, smart, beautiful, intelligent, independent, strong, sexy, everything. Tell her and make her feel that way or someone else might. Your the ones she loves. Love her and admire her too!
