It all sounds good G....just be patient and take it all in, observing and listening. I think the Doc bought drinks or paid for something on date 5. I also think I was invited inside her house on date 4 and on date 5 is when well you know.
Also, don't forget your ages. I know, I know it's just a number but you being 11 years younger is strongly working in your favor. Make sure you use that to your benefit.
