State tax filing

Hi, 

Question: My  SPOUSE lived in CA with a w-2 from CA and moved  to Texas around middle of June,  has a W-2 from there as you know Texas dose not have state withhold, also has Texas DRIVER LICENSE and rented a condo lives there FOR 4 YEARS medical RESIDENCY.

I lived with my 2 Childs  all the year in CA. 

Can I consider W-2 of TX for income CA? If it is, how about employer number? Surely has to pay tax to CA.

1-What is the status filing of us for tax filing?

2- or what is the status of my spouse in WA for tax filing?

3- and what is the status of me with son in CA? 

Thanks for your help.
