<human>: Can you summarize the given text in a few sentences?

We know each other accounts and password but she never seems to remember mine. 

Let me start by saying that my GF and I are on our summer break and she is back in her hometown. So, throughout the post, there are three locations: my current location that I would not like to disclosed(A country), my GF's hometown (B country) and China (C country).

So, last week she went travelling to China with some friends and she told me that she'd be going with four of her friends. Out of curiosity, I started to check on her Dropbox camera uploads just to see the photos she took, and none of her photos, until now, has a photo with all 5 of them together, which seems a little bit odd to me. And I found this one guy appearing in some of her photos, which made me assumed that she lied and she's travelling with this one guy. I wanted to talk to her but I don't know how to start. Should I start by saying that I looked through her Dropbox camera uploads and saw the photos so please tell the truth?

How should I approach this guys? I am really flustered and saddened by the discovery. I won't be seeing her until she comes back to A country in a few weeks. And BTW, her China trip ends tomorrow.
<bot>: Looked through GF's Dropbox camera uploads and found out that she might be lying to me about travelling with four friends, and not just one guy.
