too fast? too slow?

I feel I might be getting into the same problem I had before. Timing. How fast should I move? How slow should I move? So far it's movies and lunch dates; and it's almost perfect. I feel it's time to make it official. Perhaps Monday. I was thinking of having a talk with her, just to see where her stand is on this thing.. What do you guys think? Should I ask? Or just get on with it?
