ITM: Yes, this is normal. FIrst of all - it is a business deal to your lawyer and to his lawyer. Second, as Mish says - this is YOUR life. It has to work for YOU. It IS hard to be distracted at work but there might be some info she is trying to get your input on and truth be told - most agreements are made during 9 to 5 hours. That doesn't mean to settle but do remember that there has to be some give and take on both sides in order to reach a satisfactory agreement. And a good agreement works for both parties.
You will never get everything you ask for (well, it's not likely) just make sure you can live with what you do agree to. Prolonging it is expensive too. It's kind of like selling a house - sometimes you take less so you can get it done with sooner and stop paying out more on that house.
Anyway - the good news is that your lawyer IS working for you. There is some action. You need some movement in order to Gitter Dun.
