I'll give you a little aside story here that I think will give you some clues to just how difficult dealing with the 'other' side is.
When I arrived at the clinic were we are to be interviewed my ex is already there with the three children. They are excited to see me and there's a group of us with all three talking at once and wanting to show me stuff and tell me things.
The expert comes out to say that they'll be a break of 15 mins. My ex is straight on the mobile/cell phone to some-one and then announces that her and the girls 'have to go out now'. So they do.
I decide to go for a walk too. So I wander around the clinic and spot a big people mover that know. Inside I can see the sun gleaming off the bald head of my ex-father-in-law. I keep ambling, but it's pretty obvious that the call was to him.
Rather than risk having me spend 15 mins more with the children than I am entitled to or, god forbid, spend some time with little Sarah - they have to be taken away from my presence!
The prick! It's his lousy money funding this farce - I hope I have spent a heap
Just to play with his mind, I walk around the building and go via the other direction, so he can't see me return!
