<human>: Give me a shortened version of the text

My girlfriend went away for 10 days as one of 6 leaders at a camp for adolescents. She showed me her photographs and some of them hurt me a bit.

There are photos with another leader (male) hugging her intimately while smiling for the camera at a party. Another one where she is sleeping on his shoulder while he rests his head on hers (this one hurts the most for me).

When she hugs me or rests her head on me, I think it's something special and a way of showing she loves me. But after seeing this, I don't know what it means anymore.

When she came back she said she had the time of her life.

I think about these pictures a lot and they hurt. I think I trust her, but seeing this in my face is difficult. Am I jealous? Should I tell her? Is it her, is it me? Not sure what to think of the pictures.
<bot>: Came home with pictures of her and another guy hugging and having fun. It hurts, what should I do/say/think?
