No he may not. Spouses have a legal and mutual obligation to provide financial support to each other for basic expenses of life such as food, clothing, shelter, medical care etc. These are know as necessaries. If your husband is not providing you with these necessaries, you are allowed to bring a civil lawsuit against him to provide the necessary support. This is provided for in Washington state law in the Revised Code of Washington Section 26.16.205, which provides in relevant part as follows:
Liability for family support—Support obligation of stepparent
The expenses of the family * * * are chargeable upon the property of both spouses * * * or either of them, and they may be sued jointly or separately.
Additionally, if you are considering divorce or separation, you can make an application to a court for what is known as pendente lite support, which mean your husband can be forced by a court order to provide financial support during the duration of the divorce proceedings until a divorce is finalized and a permanent order of support is ordered.
So, I do hope that things can be worked out between you two. But if not, the legal process can be used by you to get the necessary financial support you need.
