I have been having similar issues down here and counselling has helped out imensly.
They dont try to keep you together or anything but just get you two to talk to try to sort out your differences.
try http://www.relationships.com.au/
also I found http://www.menslineaus.org.au/Home.aspx great... and trust me the first call is definately the hardest but once you get past that they can really help you just talk through things.
get in touch with your friends... they will support you, as Sandgroper says can you take a bit of time off and visit them?
As Mrs HMS says keep coming in here to talk.
