I know you are in a very difficult place. However, just remind yourself of this. The way things are now is not the way they will always be. I can't tell you what they will be (my crystal ball is broken and sometimes I wish I had one!:. Things are always changing.
Be cordial. Think about what example you are setting for you children and let that help guide some of your actions. They are watching you. I know this high road is treacherous (it has pot holes, no street lights, etc). However, when you *relax* a bit and do what you think is best, you will have a much easier time. You don't have to decide what the future looks like. It will present itself in due time.
Hang in there!
