One of Snodderley's wise counsels is to wait and let the answers come to you.
Of course you hurt, and you cannot think your way out of hurting. We practise detachment but it takes a long while to be able to do it. It is normal to feel hurt, abnormal not to. They are the messed up ones, not us. If you were watching a play and your h was behaving like that you wouldn't think 'Oh he has the love of two women, what a winner' I suspect you would think what a selfish heartless and immature jerk.
He is doing what I call 'Mr Pass for oh-so-normal' to try and think well of himself. My instinct is to ignore this, or at least let it lie for a while so that if and when you do reply it is a response and not a reaction.
If he follows it up [and as you know sometimes they do and sometimes they don't] you can just say something like, you didn't realise there was any urgency, or be frank and say you don't feel up to dividing the things yet. Likely he doesn't either, for all his talk.
Bluntly you do not not have to meet to divide up trivia like games and CDs. If you don't want to see him at present say so. Do not lay the guilt on him though - counter productive and moving to his level. Take responsibility for your feelings, and tell him you do not want to see him at present. It is your choice. When they divorce us they have no more right to see us than a stranger does. They are very good at getting us jumping to attention.
Remember, like in The Holiday, you are the heroine of your own life
