I'm 21 and still can't get over?

time heals nothing.!choice changes everything, and it is your choice to get over it or not i suspect that your afraid to get over it because then you will have to deal with real pain, when you let him go, someone will turn up that will fill the hole in your heart then you will say to yourself i cant beleive i was hooked on that guy for so long, as they say in the movies get busy living or get busy dying,, up to you.!
