A, How you feel (after a divorce) depends upon you. No one can tell just how long it will take to grieve the loss of a marriage, i.e., it's just like grieving for a death of a loved one.
How I managed to move on was to sit down, make a list of things the needed to be done and a list of what I would like to do for myself, i.e., fun things. For every chore that needed to be done, I would factor in a fun thing as well. You will also think of him as someone who has passed on to the other side for a while.
The problem right now is that you are communicating w/him. It's opening up the wounds and leaving them festering. Limbo will do that to you if you don't find a way to keep your mind focused on other things. What you are experiencing is very normal. We all have gone through it at the beginning. So, take a deep breath, make those lists and then start doing some of the tasks. This would be a good time to discover new shops, cafes, etc. Look in your local paper for free exhibits, workshops, etc. You may need to be around people or "public" activities to help you keep your mind off of him. You'll need to try different things and when something works, stick w/it.
Think about you and your family and leave him out there to swing for a bit.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
