Since you sent it there is really not much to say. In the future I might suggest you not use the word "entitled" because it usually doesn't sit well w/people.

Example... My H said he is "entitled" to happiness hence his affair. That did not sit well with me.

Once he responds with his plans for providing for you and the children go from there. I don't know much about community property states but talking to an atty cant hurt if you need immediate support and he is not providing it.
