Hmmm, a twat indeed. Hid access demands sound ridiculous and impractical to me. And, I have no experience of this, but I can't imagine any court ordering that amount of access. As you say, he's the one who's walked away and he's also the one who makes little effort to see them when the opportunities are there. Actions speak louder than words.
I hope you're keeping copies of all these emails for your solicitor and a record of his access. I know it sounds like playing dirty, but it's time you started. Tbh, it doesn't sound to me like desperation to see the boys, but a way of controlling you, because it would take a lot of effort from you to enable that level of access and it would serious limit your freedom. Jesus, who the f* does he think he is??? Talk to your solicitor, but I can't believe they'll advise you to agree to this.
I haven't posted on your thread for a while, spook, but I always check and see how things are going, and think of you lots. Take care and congratulations on the job! xxx
