hope4,
Just to let you know, his texting/calling you constantly can be considered a form of harassment. You can tell him to stop contacting you, and that if he continues you will apply for another restraining order.
I'm not sure of the law in CA, but in most places you can get a R.O. based on harassment. That could prevent him from calling/texting, or at least give you recourse if he does.
Don't let this guy keep you from your great new job. Please stick around here, and if you haven't already checked it out, please find an Al-Anon meeting near you. You can find them to be a HUGE support in doing what you need to do to move forward in your life.
