She perhaps hasn't gotten the "everyone says" advice?
My own opinion - and I'm certainly not a pro at this and certainly don't know what is happening on the ground - is that she's given you an ILU albeit a slightly drunk one, she wants to bake cupcakes for your daughters, she's told her friends a while ago that you may be "the one" and you are being distant and stand-offish.
Have you had an honest talk with her about meeting the kids / kids meeting each other? Talks about "I see a future with you"? I know that I am moving at warp speed compared to you and to the suggestions of most on here but when B and I were talking about her maybe moving in, she was joking that "kids" make that choice in weeks and were wondering why it was taking us months.
If you in your heart feel that 6 months is the guideline that you want to follow - have you told her that? She can't read your mind.
No I don't know you from J anybody J9, but you seem to be a cautious, reserved, analytical guy who is perhaps a bit anal about following the instructions on the tooth-pick packet (Hitch hiker's guid reference). But not everyone reads the packet. What do you think her expectations and wishes are? Can you meet them? Do you want to meet them?
And for heaven's sake, if you do have a relationship talk - don't use PowerPoint slides
