I just found out that my girlfriend of almost 10 years was cheating on me. She has been very secretive with her phone lately so I attempted to access her snapchat which I noticed was her most used app. She lunged over and turned off her phone so i couldnt access it. She changed her password which i used to know. I asked her what was in her snapchat and she refused to tell me. I told her either i see what's in there or I'm leaving. She didn't say anything and refused to open her phone. We lived together for years. Now I'm sitting in some parkinglot waiting for the sun to rise so i can try and move back in with my parents. I was going to propose to her onbour 10 year anniversary of being together. The only reasoning i could get out of her as to why she did it was that "i used to be a lot nicer." God knows what was on that snapchat. I'm fucked. I don't have any friends outside of work and living with my parents is beyond annoying with all sorts of rules and shit. I don't know where else to go. I have no one to talk to. I'll recover, probably, but this is just such a huge shock. I thought she was different and that we'd always be together.
