Nonsense. Women behave and communicate totally differently in potentially romantic situation. All my deep, non-romantic Christian frienships with women taught me nothing whatsoever about romance.
You don't know them til you date them.
Well, perhaps you should define 'romance'.....
Maybe you just hang around the wrong people. Your relationships with Christian friends of the opposite sex should teach you about friendship, respect, honesty, conversational skills, and spiritual relationships. Not a bit of nonsense in it, and all important in marriage.
The romance part is easy to figure out........
