Perhaps this is a question only you can answer yourself. Perhaps you don't pay her much attention and she might be looking for someone who will. Ask yourself what happened between the two of you recently? This may have been coming for a while - but you can almost entirely rule out the thought that it was a spur of the moment decision. Females are very sensitive - and it may be the smallest thing you did that she blew out of proportion in her mind - which was the deciding factor. Talk to her if you can - the relationship may not be saved - but closure for both of you is very important. It will also help you both learn from the situation.
