Are you in love with anyone?

I used to love somebody truly, madly, deeply for 8 years. I neva cud propose to him, but last year I gathered the guts to make my feelings known to him.To my disappointment, I found out that he was committed to someone else. Now I just can't seem to love anyone again. I've pretty much gotten over him, but my heart just doesn't seem to have any love left for anyone else. I have moved on, I don't even thing about the guy anymore but wen it comes to loving again, I 'm incapable,iv become numb, I don't feel anything in my heart. Im 24. Wats wrong with me? Will I ever be able to love again? :(
