then out of no where she was like well we could all stay there tomorrow (our house), we could go grocery shopping too... I'm not sure how to take this... The whole time she was here picking my youngest up she was none stop talking to me... Very weird for how she had been towards me....
Your distancing may have gotten her attention and she's going into pursuit mode. You should react by maintaining your distance. If you make a move towards her she'll go back to distancing. So keep DB'ing. That's fine if you want to go with her above idea, but just make sure not to overreact to her interest.
