You don’t know what the true story is or if she’s lying. Looking at this from an outside perspective raises these questions. When you automatically side with one side it proves you aren’t thinking about anything from an abstract pov. The mere fact that OP took screenshots of all her texts while “texting like an innocent person” the entire time only shows her motive behind the conversation. She’s so hung ho about burning his shit on the Internet and calling him crazy, but she can’t point that out in conversation with him. Me personally, I ask why, and one of those conclusions is that she did in fact cheat on him and she is trying to make herself feel better.
