Ex-boyfriend traumatized her with infidelity. I'm sure you have. So you conclude she just has a lot of guy friends. And most especially, she needs a Savior who can ultimately fulfill her. There are various reasons why girls may want this.
But they seem to want to know that they're acceptable to the opposite sex. Maybe that's why most girls don't like them - they can sniff the attention she desperately wants from men. Just go to a retreat and watch closely. At best, she may just want another guy's perspective.
