Just make sure its all out on the table. I can tell you there is nothing worse than having no closure.... For both you and her. (like if shes got questions try and answer)
I probably wouldn't sincerely hate my ex if she would have simply taken the time to talk a bit.... but what happens will happen, and you just have to move on.
I regret spending most of my college life on said relationship (though I dont regret all i've learned from it), and afterwards I can tell you the best medicine is to just enjoy some single life, surround yourself with friends and have some fun.
