Bitcoin Address you send money too does not exist.

[lolxxxx]

First of all if you are trying to sen bitcoins to an address which does not exist say you are trying to send money to (1QJmjiAZrapPyLUDUXYsR4YkGb22rvrC7W) This address but you accidentally typed something wrong in the addressees like (1QJmjiBCrapPyLUDUXYsR4YkGb22rvrC3A) Which do not exist then your transaction will not happen.
Other thing is if you just send transaction to an address which exist but not owned by anyone then you coins is gone if you are sending bitcoins to wrong address Means that the bitcoins you are trying to send to the address never created or never ever existed then you transaction will not be processed.
