Did I make the right choice by taking a break with my girlfriend instead of breaking up with her completely?
I've been in a relationship with my girlfriend(met her online but met up a few times irl) for 5 months but knew her for a year and a half and we had our ups and downs, especially during the last month where we started arguing a lot more than usual for some problems we were going through. I thought everything was fine and that she meant every word she said when she kept saying she'd love me and only me forever, however a few days ago I discovered a discord server she was in. Inside that discord server I read through the text she sent and I found out that two guys there were trying to flirt with her and that she NEVER stopped them or told them she had a bf. After I tried to ask for explanations I dug deeper and found out one of these two guys was a 21 year old streamer who kept calling her his "girlfriend" and that she NEVER said anything about it nor stopped him. Because of this, we decided to talk and call about it and I made her show her texts in dms with this streamer. What I read truly destroyed me because he asked her if she had a boyfriend and she answered that she does have one but I treat her "badly"(which I'm not trying to minimize but it was definitely not something really that true, we just often had disagreements on ways to deal with the relationship). The 21 year old streamer, after she sent that text, suggested her to leave me for someone else to which she answered "sigh who, I'm too dependent and attached", without rejecting the option completely. The worst thing about all this is that the streamer answered her by saying "You have me, if you want you can just wait 1 year for me" and she sent a text in which she said "I can't just cheat on him". The thing is, that this last text was edited and I don't know if it's the actual true one, but I can say she blocked every one of these guys a few days after she did this and before I discovered it. I don't know what to do anymore, I told her to wait a few months and made her promise to never try that shit again with anyone else and she looked genuine, she looked really remorseful: she threw up a lot of times, went to the hospital because of this, she's admitting everything to her friends etc...but should I get back with her in a few months if she actually changes or is it a lost cause? (please don't take into account it's long distance, just I beg you to answer my question)
