Basically, the question seems to be how exactly single Christians should relate to members of the opposite sex in that large and awkward zone between "we've never met" and a deliberate dating or courting relationship. I won't repeat the full history lesson here, as several Boundless authors have already discussed it (Joshua Rogers most recently, in his excellent piece "Your Friendgirl Deserves Better").
Essentially, the historical reality is that until 30 or 40 years ago, long, intimate friendships between men and women in which each served as the other's emotional confidante, relationship adviser and "best buddy" were far less common than they are today.
For now, let’s just focus on the least daunting of the three, introducing them to your mates…Whether you’ve just met, or you’ve been on a few dates, do you feel ready to introduce your girlfriend or boyfriend to your group of friends?When do you think is the right time for a couple to take this step?So is the trend toward intimate friendships between single men and women a good thing? If you haven't read my previous articles on biblical dating, you'll be helped in thinking through this issue by reading "Biblical Dating: How It's Different From Modern Dating." Based on some of the principles found there, let me offer a couple of practical reasons why I believe such friendships to be generally unwise, and then I'll suggest a positive role for friendship among singles in the Christian community.
In this series of articles, I've raised several biblical principles regarding the way we should treat our brothers and sisters in Christ.
“Even if the two of them have split, emotions take a while to heal, so it’s unlikely that the friend is going to be okay with it.” But not all relationship experts see it this way.
