Dazed, This is a classic scenario. You DB your butt off, and the WAS notices, and things get better between you, but the minute you pursue in any way, they run away with their tail between their legs and hide like frightened animals.
Grumpy is right, go back to DBing in a serious way. It was definitely working for you. You were communicating daily - GOOD. She initiated some of the communication - VERY GOOD. Spending more time together - GREAT! But give her a couple of days to think about what you said. All may not be lost. You've been talking more and enjoying each other's company so perhaps it's not a bad thing for her to know where your feelings lie. She may be thinking about what your text said, but also realizing that the two of you have been reconnecting too.
