I met and started dating this woman in her upper 20's about 1 month ago. She basically quit returning texts and calls a week or so ago. We hung out several times, and never had any problems. I spent one Sat night and all day Sunday with her. We spent the day w/ movies, and got very 'close' physically about 2 weeks ago. About a week and a half ago, I asked what she was looking for w/ me. Again, we only had known each other at the time for about 3 weeks, so maybe it was quick to ask, but her body language, and other signs were very positive to me. She slowly started being less receptive and not calling as much, etc. Now I haven't heard back from her for 3 days! I have tried to call and text 4 or 5 times. What's wrong? What should I do?
