Am i destined to move on? Or will my heart just hurt?

Okay, so my bf and I broke up over a month ago. And yes, I was healing. I knew there would be side effects because we had something really good and it could have lasted. But things happen so I was willing to heal. But now my subconscious is constantly filling my head with dreams that he'll try to get me back some how. I was healing,now I'm hurting again. Am I destined to love him forever, and maybe one day we'll be together? Or what? please help.
