The way that I won my girlfriend over is just plain and simply being an asshole. I'm not saying beat her and cuss her, but just act like you really don't care what happens in the relationship. When a girl tells you to call her, don't go home then call. Wait a day or two. Make them wonder if you are going to call or not. It always works. Like CTD said, when they say they are going out, just say well I'm going out too.
See with me I have always been a jealous type person. But with my girl I'm with now, when she says she is going out or going to do something then I say well if you're going to go do something then I'm getting with my friends tonight. Needless to say she never goes out cuz shes always afraid of what I'm going to do. So that's a good thing.
