<human>: Can you condense the text into three sentences or less?

Like I said my [25M] girlfriend  [25F] of 1 year went on vacation for two weeks with two of her friends (F)  back home (another country). Before she left our relationship had been amazing. We celebrated our 1 year anniversary and said I love you to each other for the first time about 2 months ago. 

She had this trip planned back home for a while and I wasn't invited. She said she was visiting her family and just wanted to relax with her friends and be back home. I was fine with it. She promised me she loved me and I had nothing to worry about.

Before she left we saw each other and told each other how much we loved one another and she promised everything would be OK. Once she got there we barely talked. She didn't have cell access but we agreed to email since she would have WiFi. 

When she was there there were a few days I didnt hear from her at all for about 36-48 hrs. Isnit unreasonable to expect her to write me? I would write her messages telling her about what I was up to and she would do the same and she even sent me pictures. But sometimes when I would ask questions about what she was up to she would completely ignore them.

I felt like I could trust her when she left but the no contact thing really sketched me out. She still kows a bunch of people back home and j know she was going out to the bars pretty much every night. I'm just worried something might have gotten out of hand.

She asked if anything had happened in a message and she said obviously not. I'm honestly not sure why its obvious because I have little to no idea what was happening.

She comes back today and asked me to pick her up from the airport. I'm basically having a panic attack because I'm upset about her lack of communication worried something might have happened and torn between trying to act like everything's normal and freaking out. I need some guidance...
