"I'd sure like to see a positive change in her in her dealings with me regarding the kids."
Try to think of a way to communicate this ^^^^ to your your Ex without it coming across as blaming (even though the blame seems to be clearly justified).
Something like, "Ex, I know we have been at each other in our various interactions and I'd really like to try to find some common ground as it relates to the kids. I love them and I know you do too. Here's what I'm thinking.... what are your thoughts?" Saying "we" in the opening statement takes a little of the sting out of your comment while at the same time shows you taking some ownership as well which I believe helps to create common ground"
That's all good stuff 2thepoint. Thank you. I agree with what you've said here, and I'll use it when the time is right. Hopefully sooner than later.
