If he thinks you are trying to manipulate him, and it DOES appear that way in your posts, he is very likely going to continue to resist.
Until he feels you are no longer pressuring him... until he feels that you are actually listening to him... and his needs...
And when I asked him about a year ago, when I felt like we were misunderstanding each other, if he would please go to another counseling session with us so we could get help understanding what each other REALLY wanted and was trying to do, he told me he called the police and filed a police report because he felt like I was harassing him and trying to get him to do something I didn't want him to do (improve communication in our parenting relationship, which at that point wasn't even CO-parenting anymore). Why would ANYONE want to NOT understand/be understood by someone they need to communicate with?
