I met a man we went out on a first date all through the date he kept saying what a great time he was having and mentioning other activities he would like to do with me and then he said I was incredible and wonderful.I really felt chemistry with this gentleman. At the end of the date he asked me if I had a good time and if I would like to see him again I said yes, he called me twice the next day and then I returned his call the day after and then he took 3 days to return my call we set up a time to go out again he called and cancelled saying he received a ticket to a concert he really wanted to see and I called him and said I understand and to call me later and I have not heard from him since?Should I call him or is this a sign he does not want to see me again.Please help! Please.
