Hi Tostada, I tried to keep in contact with my W regarding the kids but she prefers to be secretive or hostile or hurtful so she feels more in control. It's best not to get sucked into her drama by expecting rational or friendly behavior from her.
For example I asked W at the start of Summer her plans for the kids. She said "none of your business, you do your thing, I'll do mine" and hung up on me. She was much more hostile but I won't go into that. So I quietly sent her my plans by e-mail cc to D12 and did "my thing". One week she took the kids on vacation and fully intended to use some of my days with the kids without my consent tho' I had made advance plans and told her so. She left me nasty v-mails. For a couple of days I was worried about the kids and felt annoyed with her behavior. But she got absolutely no response from me and at the end of the day she brought the kids back on time.
I agree with Kerry that his way is the way it "should" be. But that is rarely the case.
