Friends feel that this is to keep me as Plan B until she is confident the OM is what she wants.
This is VERY typical, especially for women. The metaphor that I use is that it's like two plates spinning on sticks; she will occasionally come back to your plate and give it a few spins (be nice to you, try to ML, throw you a bone, etc.), to make sure it's spinning while she goes back to the OM stick/plate.
