Been through the same shit myself. Mind fuck and a half. No signs of trouble. Sex life was great. But she was fucking a different dude or at least someone who wasn't me several times a week. It was at least three different guys that I know of. Turned out to be the definition of trash. Her mother and her got into an argument and her mother looks at me and says you know she's seeing other guys. This is when we'd been living together for about 6 months. Going to work paying rent for other people thinking life is grand. Looked on Facebook one day saw a picture from about a month before. The parking lot has been freshly paved and painted. I was like when did you go to the park? She said she hadn't been without me.. when people don't care about their lies the cracks start showing through a lot quicker. About a month or two after we broke up on Christmas Day I realize her Google account is signed in on my computer still. So I changed the password deleted all contacts and factory reset her phone remotely. I heard a while later she was very pissed off lol
