Washington State just passed legislation and the governor signed it on February 13. (Story from the L.A. Times). The article from the L.A. Times also includes a nice time-interactive map of the US showing how different states have changed over time to increase or decrease the rights allowed for gay couples.
The National Conference of State Legislatures has a nice, comprehensive statement of the status of same-sex marriage across the country here.
So, have a fabulous Valentine's Day, and remember, that IT GETS BETTER!
