I'm not entirely clear on your question, but it sounds like you might be asking about grounds for divorce or factors considered in divorce proceedings. Washington is a no fault state; nothing has to be alleged except that the marriage is "irretrievably broken," and only one spouse has to allege that. If the other thinks the marriage can be saved, the court might delay entry of a decree and refer the parties to mediation, but it will not prevent the dissolution from happening (you can't force someone to stay married). Because it is a no-fault state, the court is not supposed to consider marital misconduct (e.g. adultery, or I suppose "desertion") when making its equitable division of assets and debts and deciding whether spousal maintenance (commonly referred to as alimony) should be awarded.
