One thing that I have found that really works is the silent treatment. If a girl makes a mistake (Mine started to like another guy), you dump em, tell them you want it all or nothin. Then just ignore em. Sometimes it takes a week for em to come back. Sometimes it takes a couple years, but most of the time they do. And plus, if they don't come back, then you really don't need em. And if you gf fvcked up real good the first time and made a big mistake, when they come back, you said said "hell no bltch, I don't want your as*." its fun to see their reaction. So ya, tell me if you all have tried this method, because it works for me everytime. the girl I broke up with a week ago just came crawlin back today. it was great
