You call her - she calls you back. You email her - she emails you back. You go down on her. . .you get the point. A healthy and enjoyable relationship stems from a simple principle, tit for tat. If there isn't a good exchange back and forth, it becomes one of two types of relationships: controlling OR obsessive. Think about it. If you keep giving her presents and she doesn't reciprocate, what are you dating? A gold digger. If she calls you five times before you have a chance to respond, what are you dating? A stalker. Inequality is the red flag for disaster in dating. Be aware of her actions and watch yourself as well. If you're emailing/calling her a lot and she's not responding, you're likely going to push her away. Too much tat and you ain't getting no tit. Ya dig?
