gmoreno...what does she like to do? Does she like things like craft shows? If so, take her to one, then go out for dinner afterward. Surprise her. Bring a picnic basket filled with her favorite foods to her house, clear her living room of furniture, spread out a blanket and have an indoor picnic. Be spontaneous. Women (I think) want to feel special. They want to know that the men in their lives listen to them and want to be involved in their lives. So try to go on dates to places or events that have significance for her. If she is into something, get into it too. Show her that you are willing and able to be involved in her life. Women tend to hate it when they feel that they are being shoe horned into the man's life.
Always have a sense of humor and a sense of adventure.
