I do understand how you feel and in time, you'll pick yourself up and move forward. Allow yourself the time to grieve and cry as much as you need to. Allow the pain to wash over you and then release it.
When you feel better, then pick yourself up, dust yourself off and continue moving forward. Plan some things this week w/the children and get out of the house for a bit. Leave hubby at home doing his own thing. You need just as much space and time as he does to heal.
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.
