Hi leecamowol,
I must be honest, I totally shared wagon_wheel's view and opinion on your dilemma.
As a girl, I would never have agreed to go to a man's house, not only for a first date, but effectively, a 'blind date'.
But, sounds like you both got on well.
The question you now ask, about what to do next, well she has placed the 'ball in your court'. So yes, you do need to ask her on a date.
You mentioned that she lives 30 mins drive from you, so how about suggesting something in the daytime (Saturday, probably as I'm assuming you both work), you should really go to where she lives.
She has checked out where you live, you now need to check out where she lives (and get an idea of her life-style). I still have a niggling doubt about her.
Check that she;
1. Has a home
2. That she is not looking for a 'meal ticket'
3. That she is 'totally' single
Google her town and find an idea for a good day out and a restaurant for lunch, suggest picking her up from her home and the day out you have planned.
You will know from her reaction to this suggestion if things are 'regular'.
Please post again, to let us know how it is going.
