From my experience (15 years of LLL meetings) this varies. Some people never leak, some stop at some point, and some experience some leakage as long as their child is nursing. Well, come to think of it, I have heard of many mothers who can still express milk long after their babies wean. I think it has to do with your physiology, your reaction to various hormones and many other factors. So, you are not "abnormal." Hope that helps.
