If you are already separated you could file for a legal separation. I assume he continues to support you. If not, you can certainly go to court if you file either a legal separation or divorce, and get maintenance (the WA word for alimony). You are also entitled to a portion (at least half) of all the family assets including his retirement, etc. You don't say why he is wanting a divorce now, but it seems unnecessarily mean spirited under the circumstances. You also don't say how old the children are. He has a duty of support if they are still in high school or in college and under 23. You should talk to a lawyer.
