Should I feel embarrassed?

[Curious Mind]

Lets just say I'm feeling VERY down in the dumps about this. I was out at a restaurant when I noticed a group of guys and his friends staring at me. I was sitting down alone charging my phone when he and his buddies came up and sat at the table beside me. He asked me if I was getting some juice for my phone and I said yes and giggled. I also said I was texting and he said ''oh you must be popular'' and I laughed and said my popular days are over. He asked for my number and I gave it to him because he was fine and I like black guys. Well we texted over the next few days then he asked whether I had Facebook instagram or twitter and I said no, that I deleted them after a bad breakup and was a pretty private person when it came to those sites. Then bam.. It's been a month and he's never texted me since. I feel so ugly and worthless now. Why did he do that?
