been there, done that, got the t-shirt.
my ex ended things with me in october, not long after he started uni and totally out of the blue. for months i couldn't get him off my mind. it didn't help that i continued to see him and sleep with him, but in february i called it a day and told him i didn't want to speak to him anymore. i think he was quite sad about this, because he wanted to remain friends.. lol!
anyway, it took me ages to get over him fully, but i've finally done it. sure, i think about him sometimes, but then i think about my current boyfriend and how much happier i am with him, and how much better he treats me than my ex. trust me, you will find someone just as good, probably better than your ex. he's moved on, so you should to! uni will bring many new opportunities for you, so you go and make the most of it. leave your ex behind girl..!
