BDB, if you want a divorce in less that two years you have to do it on the grounds of adultery, or unreasonable behaviour.
If your (ex) wife has not taken up with another partner, nor beat you up or somehting else the court might see as unreasonable, then either she can divorce you for adultery, or you have to wait for the two years of separation.
However - separation does not have to mean living in separate houses. If, for example, you couldn't afford to move out until the house was sold, but lived seperately (ie. separate bodrooms, each did your own cooking, laundry, etc), the court will count that time as part of the two years.
