In WA, a person cannot really avoid being divorced. There may be delays, but eventually, the court will sign the final orders.
If the husband can show that you cannot be found after taking diligent efforts to find and serve you the summons and petition, the court likely will authorize alternate ways of service (such as by publication in a qualifying newspaper).
If the husband does nothing after filing the petition with the clerk, after 5-6 months, the court will set a hearing to check on the status of the case. If no one shows up for the hearing, the case may be dismissed for lack of action. Either spouses may file a new case after dismissal.
