A few weeks ago, this guy I didn't know added me on Facebook. Before I declined, I realized that he was ADORABLE. Therefore, I left it. Later in the week I happened to notice that he was online, so I began talking to him. We've flirted a little, and pretty much called each other "sexy". Therefore, there's an attraction between us for sure. He's lately, always been the one trying to carry on conversation. And he's liked my profile pictures and whatnot. So before I left the computer last night, I asked him if he had a cell phone. He gave me his number, and I got a text back saying it wasn't a valid number. I looked on his Facebook info, and the number he gave there had a 3 digit difference. I'm confused as to why he'd give me the wrong number? And should I confront him about it? Or wait to see if he brings it up?
