by the sounds of it she dumped you in your previous relationship? i say to hell with her lol... i guarentee there are about a million other women exactly the same or better... try find them rather then rekindling an old relationship... if you really want to get back with her take her off her pedestal and make her jealous... show that it doesnt bother you whether you two get back together or not because you're having so much fun being single, and dont talk about negative topics like why you two broke up... just wipe the slate clean and treat it as if its a new relationship... hope that helps mate
i personally think you should just cut her away... she obviously hurt you last time so why does she deserve a second chance?
