I'm sorry, but if a guy wants to go out with you for real he doesn't say he'll get in touch to "work out the details." He sets everything in concrete right then and there. I keep thinking about that book "He's Just Not That Into You." Yea, I know there's a movie coming out but in the book the author is very good at describing the way guys classify women as top tier, second tier, third tier... Top tier women are the one's he wants to see on Saturday night, that he makes very specific plans to see, that he's willing to do anything to get with, making it very clear to her that he's VERY interested. The others are his "backup" plan, in the event he doesn't have a Top Tier on Saturday or he just doesn't want to be alone on Thursday night (Hello. Booty call). I recommend all single women read this book, by the way. The author got hate mail from men who were angry he spilled the beans on male methodology. I found the details in the book simultaneously nauseating, enlightening, and liberating. As he pointed out, when you can read their actions and figure out they're just playing games with you, that they don't look at you as Top Tier it frees YOU to move on and find a man who does.
Frankly, your boy is an ass and he's screwing with you. He doesn't know how badly he's blown it by messing with a great chick (and using your friend to help) but you do. Forget him, don't waste a night sitting around waiting, and move on to better men.
I probably shouldn't be watching BURN NOTICE while writing this. It's giving me ideas on how I'd like to handle the little a**hole. Seriously. Forget him.
