He's Just Not That Into You

There is a book called He's Just Not That Into You by Greg Behrendt and Liz Tuccillo, I haven’t read it, but I need to. It seems like every guy I start to get involved with disappears. I’m having some trouble with Dru. When I left a week ago from the Atlanta airport I thought for sure things with Dru were going to take off. He was so sincere in his goodbye and we had such a great weekend. However, since then we have barely talked. We talked on the phone a lot on Thursday, which was nice, but since then we only talked on Sunday when he called but I lost signal and told him I would call him back. 5 minutes after, I called back there was no answer. After another hour passed without a call from him I texted, “I called you back.” I got no response and haven’t heard from him since.

Am I missing something? Things seemed great on Thursday and fine during the few minutes on the phone yesterday. I think I need to read the book, because apparently he just isn’t that into me. I am so confused. I know he is busy with his job, and doing whatever else, but I don’t understand why he doesn’t call more often?

‘You could call him’ is a response I would expect after this story. My response to that is lame, but if he wanted to talk to me, he would call. Again another response, ‘Maybe he thinks you should call.’ He is very old fashioned, and I am too. I think it is the boy’s responsibility to call and pay for dinner and all of that good stuff. And we have kind of established through habit that I don’t call him.

I am in that horrible spot where I don’t know what I should be expecting because I don’t know “what we are.” And having that talk is something I would really rather him bring up. But here I am getting mad that he doesn’t call enough. What is the deal? Am I overreacting or being childish? Is he just not that into me?

Any and all advice will be greatly appreciated!

UPDATE: Dru called this morning a few minutes after I got into work. I was contemplating answering it because I generally don't take personal calls at work (...but I blog, facebook, check email etc). I figured I should answer it because I have been complaining about him not calling. Turns out he wants me to come down next Thursday and go to a Halloween costume party for his company. Friday is a party at his house, and Saturday is a big game at Ole Miss. Here is why I didn't immediately say yes (although I desperately wanted to):

1. I've never been to a company party...let alone a company costume party! I originally planned on being Amy Winehouse, but I'm guessing that won't be appropriate! :)
2. Roomie and I have been planning (for months) to go to the New Kids on the Block concert that same night.
3. Roomie and I have also been planning to go to Chapel Hill the next day for Halloween for quite some time.

My proposed solution: I have talked to my sister and offered my NKOTB ticket to her free of charge to go with roomie (they get along just fine). She says she will probably be able to go. Roomie should be OK with me missing Halloween, because she has plenty other friends in Ch. Hill and I have talked about missing it before. Your thoughts?
