Pastoral Conundrum

So I chatted with this girl, right, because I was worried that she's leading a double life. Christian on Sundays and non-Christian when she's with non-Christians.

When I brought it up, she cries. She told me that there is a problem and she's talking to someone about it. I was blocked. And it left open the question of what the problem is. Is it a sad problem? Or a sinful problem?

What do I do? There may be nothing to worry about. And there may be something to worry about. My hunch is that it's a sinful problem. If I say something *just in case* there was something to worry about, it's ok, right? since a Christian should be able to understand that concern.

... So anyway, I hope to speak to her again and tell something she already knows. I'll going to tell her the gospel. It's a comfort if there's a sad problem and it's a rebuke if it's a sinful problem. If anything happens, I'll post!

What would you have done?
