A jealous girlfriend is like having an investigator every day of your life. You will fill that you are being watched over with the things that you are doing. You will always have someone checking on you and what you are doing. For men, they hate this concept of being watched or guarded. There should be freedom in terms of the things that they need to do. On the contrary, jealous women often are the ones that love you the most. They are willing to look bad just to protect you from the things that will destroy your relationship.
