<human>: I (f/19) and my ex(m/22) broke up in November after dating for 7 months... April 3rd would of been a year and well I'm not sure how to handle the upcoming sadness that will be present that day. I honestly hate my ex but at one point he meant a lot to me and well now... I'm not sure I even want him to mean something. He's treated me like shit, like a princess and then like shit again and well I hope he enjoys his new found happiness with his new life that he's created for himself. He recently texted my mother and told her about piercings and pictures posted on reddit to be a dick and then 11 days later.... Easter Day he texts me saying happy Easter and that he missed me ish.... I wish he'd see this so he'd understand that I fucking hate him and he can go fuck himself. But anyways I still get sad thinking that what could of been our 1 year of happiness is coming up and the douche of a guy ruined it by changing into the guy he told me he'd never be.

Can you summarize the given text in a few sentences?
<bot>: fuck my ex and everything he once meant to me. 1 year could of been, would of been, should of been is down the drain because of stupidity.
