Hello ladies and gentlemen, I have a relationship question. I've been talking to this woman for about a month and half now. we've taken things slow. Only texted the 1st 3 weeks, then started talking on the phone for the last 3 weeks. I finally asked her out for dinner to meet face to face. We were supposed to meet Wednesday but I had to postpone to Thursday due to my pay check not hitting my account until late. She was ok with moving it to Thursday at the same time and place. It got to the time to meet and she never showed up. Later that I got a text from her that she had slept all day and overslept and never ment to stand me up she promised. This is where it apparently goes south. Other than apologizing for not showing up, she has basically stopped talking. She hasn't said a word today. I've tried texting her , calling her, she's even been on Facebook today and hasn't answered there either. Do you think she's moved on?
