There are many reasons people 'unfriend' other people on Facebook. Some people go through their list and delete people they rarely communicate with. Others delete people that they don't have much in common with, and still others may not like some of the things you post if you are a person who has strong opinions. Unless they tell you why, you may never know the exact reason.
The only way to find out is to ask them directly otherwise you wont know the real truth
