Why do I still hurt, how do I survive this unbearable pain at the moment?

Its been 5 months since I became a jilted bride. Long story short, my ex fiancee cancelled our wedding two weeks before our day. His reasons now, are "he had doubts". Doubts were based on false and made up rumors that he heard a long time ago. Rumors were started by jealous people. Im now taking him to court to repay money I spent on the wedding. If he didn't want to marry me, he had enough time to stop the engagement and not plan everything out like he did. So why do I still miss him and why do I still hurt??? Ive moved on and beginning to date, but my heart still aches. I do things to keep myself busy but at times I still find myself thinking of him. Yes I loved this man very much and I know he's not good for me but why do I hurt??? This pain will go away and I know time heals all wounds but geez this pain is so unbearable............I at times, would like to call him and talk to him but I cant (civil lawsuit). I at times, would like to call his parents but again I cant (parents will always back up their children no matter what). How do I stop the hurt/pain and the missing him???
