I have not received my bitcoin after 2 days and 115 confirmations I have sent my first Transaction and waiting for it to arrive at another address but when i click on the Transaction ID 1 of the addresses is Spent and the other is Unspent? It only required 3 Confirmations but is now 115? Where is my bitcoin and how do i receive it? 

Thanks in Advance
1 of the addresses is Spent and the other is Unspent? 


The simplest transaction has one input and two outputs. One output is the amount to be transferred to the destination-address. The other output is the left-over change being returned to the sender (to the wallet containing the sending-address).

One way of interpreting what you wrote is that the recipient has already spent what you sent them.

Another way of interpreting what you wrote is that you have subsequently spent the change in a second transaction.


  It only required 3 Confirmations but is now 115?


The transaction is confirmed. It is not pending. If you wait longer nothing will change.


  Where is my bitcoin


Someone has already spent it (i.e. spent the amount sent or the change returned). 


  and how do i receive it?


It has already been received.



You don't say explicitly that you "own" the sending address and both of the receiving addresses (perhaps in more than one wallet) but if so, your wallet has been compromised and you should immediately move everything into a completely new cold wallet 



lets look at the transaction

Transaction: 0ec3e57ee26a68f73030f331fa18184bc3290833fb5b40509caedbd434c99301

Source of funds: Address: 18gLw9DF8aBW2PzY3rVi35bFiuSTNgiv7s 
                 Amount:  0.02849847 BTC

Outputs:         0.02054938 BTC to 16FsHnvTqnYrvdPXTH4c7tXD8ZE4r8rXJg - (Unspent)   
                 0.00781349 BTC to 1NtLEd3y5wEmR3bsQ1LEeN6g8H3DbxSmiU - (Spent)


Only you know which is the amount transferred and which is the left-over change. So only you know whether the amount or the change has been spent.
