Oh my I want to hit him with a bat.
"We don't need to define your week / my week"
Yes, yes you absolutely do need to define contact times, so everyone knows exactly where they are. And so you Polly do not end up doing all the parenting, because Geller wants to have 50:50.
He desperately wants you to organise everything and to shirk his parenting responsibilities.
Seriously Polly, get contact hammered out very clearly, I'd be inclined more towards a 70/30 with you having girls majority of the time because he is not fit to parent.
And also because your financial settlement should reflect the extra responsibility you will be taking of your children.
I wouldn't meet him, I wouldn't respond.
I hope GP appt goes well, I find when I'm stressed and run down I get sick too, I once had back to back raging thrush for months, GP thought I was diabetic, was horrific.
Take time out for yourself, rock your leather jacket putting out the bins (because you bloody can), hope your break is amazing also. I know MN hates the term making memories, but make amazing wonderful happy memories with your girls and for yourself.
Also realised why I keep saying go for the jugular, Carpe Jugulum, it's the Terry Pratchett book. but I do feel you should totally sieze the feckers throat (metaphorically in your divorce)
