What Are the "Rules"?

I'm fascinated with the dynamics between guys and girls in general, but in particular, the romantic dynamics between Christian men and women. I, like most of the contributors I assume, thought when growing up that I would meet someone in college and be married by age 22. Alas, I am 26 now and still single. I've dated around, even dated a girl for six months about 9 months ago, but I haven't had a "girlfriend" since I was 20. I'm not sure how we got here, with so many great Christian men and women still single, but I think it has to do with a confluence of many factors.

Sam's Perfect Storm of Factors Impeding Marriage (in no particular order)
1. Sexual Revolution - no reason to get married (guys especially) if you're getting all your sexual needs met

2. High Divorce Rate / Children of Divorce - our generation is skittish with making a marital commitment when they've seen their parents and others get divorced so frequently.

3. Increasingly Knowledge-Based Society - back 30-40 years ago, a man could graduate from high school, get a factory job, and support his family. Now, a bachelor's degree is a minimum requirement for a decent job, if not graduate degrees.

4. American Society's Fear of Growing Older and Facing Responsibility - also known as "Peter Pan Syndrome" (at least for males); see also the popularity of such movies as Old School and Wedding Crashers

5. Joshua Harris / Fear of Being Hurt in Relationships - Did I read "I Kissed Dating Goodbye" as a teen? Yes. Did I buy into this garbage for awhile? Yes (probably for too long). For those of you who haven't read it, the title says it all. The basic premise is that everyone should group date for awhile and then eventually pick someone out of your group to start a courtship with. It's something that sounds great in theory (kind of like communism), something in which relationships could move from group date to marriage seemlessly with no risk of anyone getting hurt. Which leads me to my current girl situation:

So I'm interested in the roommate of my friend's girlfriend. I met her a couple of months ago at a Super Bowl party but was discouraged by my friend and his gf to call her. They advised me to wait and get to know her better in a group setting so she'll feel more comfortable around you. I follow their advice and wait for about a month or so, which in the mean time, I've hung out with her in groups another 3-4 times, going out to lunch with her in groups a couple of times after church. (Please note: I didn't ask my friend and his gf if it was too soon to initiate contact. Maybe I should have in hindsight, but I was tired of feeling like I was back in 7th grade, asking a girl's friend if she likes me). So last Sunday, I shoot her an email asking for her number, saying I'd like to give her a call sometime. Still haven't heard anything back yet.

I certainly don't think I have an overinflated view of myself, as Boundless might hypothesize (see "Brother, You're Like a Six" article). I think I'm about an 8, to be honest, and I have pics to prove it!! :) That being said, I don't go after girls "out of my league" and think she was in my range. My question for the ladies is:

What are the rules in dating in general for Christian women? I completely disagree with the Boundless article "Where's the Motivation, Guys?", as I am one of the guys that doesn't mind calling a girl and risking rejection. I think a big problem in the Christian dating scene is that there is no standard set of rules to follow. For one girl (my current interest apparently), you need to have known her since kindergarten and be best friends before you can dare to ask her out or else you're a creep and a pervert. Then you have other girls who are wondering why Christian guys are such wusses and are afraid of women and physical contact with them (see: "Where's the Motivation, Guys?" article). Just from my perspective, the reason guys don't have motivation is because guys that do (like me) don't have much success unless you put in time to be "group hangout" friends. Maybe it's just living in the South (Dallas). Is it different other places? I lived in Chicago for a couple of years, and it seemed like the Christian women there were more open to dating to get to know one another. They didn't feel like they had to decide if they wanted to marry the guy before going to dinner with them. Please advise, oh wise fab females. I'm going to go fill out my eHarmony personality test now...
