Heres a very brief summary of an other-wise deep conversation:

Girlfriend has been acting suspicious, I went through her phone a month ago and discovered this. Many people recommended breaking up but i wanted to see this unfold first. 1 month later heres the final conversations:

Girlfriends ex has been trying to get back with her for 1 month now. He texted her wanting to talk, she said she has someone now. Eventually they spoke about their past relationship over text, she got a bit emotional, puppy eyes emojies, "how did things end this way". She even admitted to wanting to have a more stable relationship with him, that he wanted only fun and nothing serious. He told her he wanted a stable relationship with her, but that hes moving to Bali next month, wanted her to come with him for a year.

She seemed open to it initally saying she has never been out of the country before, told him she would think about it and that she lives with her brother and has to think about many things. No mention of me. Eventually he gave her a few weeks to think and didnt bother her over text, recently he asked her again to follow up, and she said "I told you I already have someone" He never replied after that one.

Guys I have a question:

Many many people here commented that she wasnt loyal. Hes the one that got away, shes always going to be thinking about him while with me. At the end of the convo she refused to meet up with him after all the attempts, based off their convo it sounded like his final try. She even at the very end of his final hail mary, told him that she has someone.

***What do I do? Do I still leave her now. Should I be happy she rejected him and never met up with him once?
