Eh, I'm probably only inferring from my own experiences, but when I got answers they never sounded right for me. And I know of so many people that got hung up on trying to find an answer that was right for them and never hearing what I wanted. What I'm trying to say is, the answer that Sarah may give you as to why she ended things may not be the answer you're looking for, and that shouldn't be a motivation to find one for yourself (because, again, only inferring from my experience, you may not be in the right mindset right now to hear answers).
