It will return back to once it came from.
It happened to me last night when I sent too low of a transaction is it was rejected and purged from the blockchain. Atleast that is what blockchain.info said when I check the hash from there.
The transaction never made it to the blockchain (while unconfirmed) so it cannot be purged from the blockchain. Rather blockchain.info's node decided to drop the transaction because it was unconfirmed for too long. Many nodes will do this, so the transaction appears to be "forgotten" by the network. When that happens, you can respend the Bitcoin.
Anyways, this thread is a few days old and the transaction has already confirmed, so I will lock it. If your post was deleted just now, that's because it was either off topic, not helping the OP, or repeating what had already been said.
