What should i do with my ex?

well,i'm back, i can see that my story never ends,i recently confronted my ex,and i decided to move on, but for some reasons i still think of him, wich is normal, after the love story we had,but my problem with my jealous ex ,is that he didn't leave me alone,he still calling me and even sends me presents wich he never did it before, so i was wondering,may be he still in love with me ,may be he finally knew my importance to him, i really don't know what to do,do i need to reconsider my first decision to let him go or what????????
