I'm glad this part is finally over for you. It's been a long haul/struggle and one that has taken up quite a bit of your time lately. Hopefully you will be able to now focus on your children w/o having the additional worry and also on your future.
I'm sorry it came down to this, but I agree...you'll be able to walk tall, hold your head up and yes...sleep at night.
I can believe he's called you. You do realize it's not over w/him calling you and needing you? He's still attached you in his own sick little way, so please be prepared for more calls about minor things and/or w/excuses to just talk to you.
Take care.
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.
