["Warning! this transaction is a double spend. You should be extremely careful when trusting any transactions to/from this sender."]

I have a Blockchain.info account. I wanted to send 1.1489 BTC to a friend. I clicked on the send button in my Blockchain.info wallet, I paid 0.0001 mining fee. After 8.5 hours I have this message:

"Warning! this transaction is a double spend. You should be extremely careful when trusting any transactions to/from this sender."

Wtf? How can I double spend when I am sending from my blockchain info account?

The recipient never received the money, but 1.1489 BTC deducted from my Blockchain.info account balance. I am an average user, all I did clicked on the send button to send this 1.1489 BTC to a friend. This is BS. What on the earth I could do wrong that I have this double spend message? I sent the money from my  Blockchain.info wallet.

Could you help figure out what happened and how to fix this please? 1.1489 BTC is a big money for me to loose for nothing.

The transaction hash is

and I wanted to send to address

this my friend's BTC address where I waned to send the money.

Maybe this is why people don't want to use Bitcoin because such things happens, never mind the many scams on the exchanges.

i always liked vericoin, it seems the coin is back. is it back, perhaps it is time to buy?
