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

It's been a month since my breakup, and actually life has been good. The break up happened suddenly when after four intense months I told my ex that I loved her, and she said she didn't feel the same way. She left a week after to go travelling for two months. Didn't speak a word since I walked out the door.

Fast forward a month, and I saw one of her friends at a BBQ. I found out that when I came into the picture, she was still seeing her ex boyfriend. I was rather inebriated when I heard the news, and I wasn't sure if she was cheating on me when we became exclusive. So I broke NC, and asked her what the story was.

I was a little surprised to open the message saying "I was just thinking about you and thought about messaging you today" (don't overanalyze it). She confirmed that when we were casual, she saw him a few times. Whatevs. She said that she thought she could get over him, but had a hard time moving past her last relationship (2 years+). She said it definitely created distance between us. She then said that it truly wasn't the case we broke up, instead it was "just not meant to be. At least I didn't see it". She ended the conversation saying she saw one of the birds we laughed at together while she was traveling and that's why she was thinking about me. I won't be contacting her anymore since her tone was distant and didn't imply anything more.

I am now seeing other people and happy to be moving on. I won't be waiting for her. But like the curious creature I am, I was wondering if when a girl like her situation says "it wasn't meant to be", is that always final? Is there ever a future moment where they turn around and suddenly feel differently?
<bot>: Broke up with girlfriend, a month later find out she just wasn't over her last relationship. She maintains we weren't "meant to be", but is that reason always final?
