You can't "add" a secret key to a public one - otherwise, there wouldn't
be much point to public key cryptography...
You will have generated a secret key when you generated the public key -
they're generated together. Somehow you've managed to lose the secret
key. You need to look around in the places where you generated/stored
the key to see if you can find it. If you can't find it, then I'm
afraid that you're stuffed - you won't be able to decrypt your encrypted
information (short of brute-force cracking it).
Sorry for being the bearer of bad news...
