I had a girlfriend in college for several months who, I later learned, cheated on me for half a summer - while eagerly talking about marriage. She eventually manipulated me into breaking up with her by being evasive, controlling and basically impossible to have a rational conversation with - but not until after she'd been fucking this other guy for two months. Piecing things together later, I learned from her friends that she was a compulsive liar and basically a terrible person. They'd wanted to warn me but couldn't because she was their friend first, and as her boyfriend for just a few months I'd only been shown the good side of her until about the time the cheating started. Learned a few lessons from that fucked-up mess.
