Textgame is solid man. You did enough pushing for the date pitch, so I would pull back now. "Solution?" or "So..."

I would say something like "After class? Or is that past bedtime"

My suggestion is if she is a doctor better not to date cuz they don't have time.next u need to ask her "what ur schedule like". and there is no sexualizing in conversation and it looks boring it doesn't make her to invest her time in conversation
