Do any of you hate or despise an ex?

Do any of you good people hate or despise an ex? if so please give reasons and why? I'm not shy so let me begin i wasted a year of my life in a relationship that i knew was going nowhere, i guess i felt pity for her and might have hated myself with self loathing. I was 32 and felt washed up so i took what came along and immersed myself in the relationship but as always by random chance i met another lady, she was everything i wanted, kind good natured no ties intelligent and worked her as's off in her job. We fell in love instantly, but i can't cheat and never will so i left it at that. She was always in the back of my head, eventually i took a leap of faith and left the ex seeing how she was going to kick me out anyway as the signs were all there. I keep a clean house even though it was her house and she was a complete slob, her kids were filthy so after doing a full days work there she was sat on the sofa eating doritos and i cleaned the house after her fat useless as's and her kids. One day i let it be known i was sick of her and her kids and i bogged of to the bar to get seriously drunk. While there getting seriously drunk i phoned my now fiancee to come get me lets make a go of it, she was there asap. I went back to the house got my sh'it and left. I know hate is a strong word, the ex did me no wrong but i do hate her, i wasted a year of my life on a complete slob and her kids. (Not mine, dad was still about) so whats your story?
