Just leave it I think everything is fine its just a bit weird around you guys right now.A guy at work that I was friends with and I had no interest in asked me out at work and I was standoffish for a while to make sure I didn't give him the wrong idea. I had gone for coffee with him and everything but stopped that as I realised he thought it meant more.Leave it for a month or so and things will get back to normal soon enough, she is just backing off so you know where she is at.
