I've seen some of my best friends naked...but then again, I saw them naked before we became friends.

This friend of hers is obviously located near to where you guys are. I'd be uncomfortable with her decision to invite him to see her pictures. Upon discovery, I would've expressed my discomfort to her and mention that I would've appreciated the opportunity to discuss it with her first. As to mixed signals or misleading statements...can't help you there. You either trust her or you don't. That's your call.

Though I am different from you,
We were born involved in one another.

For it was not into my ear you whispered, but into my heart. It was not my lips you kissed, but my soul.

Complete surrender should not just come at moments in which one faces overwhelming odds, but in the calm when it seems one is personally in complete control of one's life.
