Is it wrong to reject a guy who made me wait fot an year to accept my proposal?

I am mad at him for wasting an year of my lifetime. Due to him I have stopped focusing on other things of my life since an year. Now I feel that he doesn't deserve to waste a bit of my lifetime so I want to reject him. Is it wrong to do this? Or am I doing right?
