Why am i having these dreams?

almost every single night my dreams start off about well...this is pathetic...my EX! omg shoot me. no wait I'LL DO IT MYSELF! damn it! ok well its eating me alive and i hate it. each dream is about the same thing it just plays out differently each time: we end up together again. how sweet! NOT REALLY! esspically when i'm trying and FAILING to get over this guy. i want to move on. i want to find some other male to pionately make out with and tell all my secrets too. but it doesn't help that i keep getting these unwanted nightly visits! HELP ME! how do i stop the dreams??? i've been hurting for a long time and i just want to forget about him :( :( :(
