Regarding the co-parenting thing...I wouldn't ask him to write it down. I think you should do it yourself and ask him to respond. If you have him do it first and then you don't agree with something he comes up with you will be in a position to disagree with him...not good if you are trying to keep the peace.
Now...My H was the same way...acted like I was a leper and couldn't wait to get away from me. As hard as it sounds...just let him stay away. If he is going to miss you he has to have a chance to see what it will be like without you.
