A girlfriend likes surprises. She likes them a lot. Surprises mean that there is something new about you that she was unaware of, and the element of surprise makes her feel close to you. Surprises are like little gifts that reveal new aspects of your personality. You don't have to break the bank to surprise your girlfriend because planning and creativity can make your surprises as wonderful as they can be. Reserve one day every week as a "surprise day." On that day, do something that you wouldn't normally do. Maybe take her to a nice romantic place or cook a nice meal. Perhaps you can plan a vacation or a mini-vacation. Anything you can do to give an unexpectedly positive experience to your girlfriend will make her happy.
