My fiance of four years was seeing another man for a year before she bothered to tell me.
er... you were engaged for four years without getting married?
Call me tactless, but maybe she got impatient. 
You're Tactless

Seriously though, the reason why was because we couldn't afford to get a place together, she must have gone through about 5 jobs in those 4 years and was sacked from 2 of them. To be honest, she'd been running me round in circles for a long time, I was just too blinded by my own 'addiction' to her to see just how much of an idiot she was making of me and those close to me. This is a common mistake in both genders. There's a lot more to the story, but as an example, I had to have major surgery on my jaw, and when she saw how bruised my face was, and the fact that my teeth had to be wired together for 6 weeks, she decided she didn't want to see me again until I'd healed. It still infuriates me that I was stupid enough to accept at the time, but you live and learn.
In hindsight, I don't regret us breaking up one bit, lesson learnt, and I came out of it with something far better
