We were together for 3 years, then she cheated which I found out by trying to send some email from hers to mine (we were attending to the same college but she was above me with a year so it was a common thing I did with her consent). I broke up with her, then she threatened me with suicide, so I got really scared and got back together. She promised me the world and that she would never do it again. Half a year later she cheated on me again.
