You may not get a response to your email for a while. Your h needs to digest it and he's thinking that if he remains quiet, you'll settle down. Keep in mind, they don't think like we do and sometimes they go into their shell for a while after we have stated what we need to do to protect our children and our assets.
Sit quietly and patiently. If he doesn't provide any money this week, move forward. You've advised him of what needs to be done and if you back down, he will think you are like the little boy who cried wolf all of the time.
Sometimes, we have to file in order to stay afloat. Stop second guessing yourself...you did what you needed to do and you've been more than fair while he's been out on the street. Now, it's time to take care of you and your boys.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
