How are you feeling today OP ?
It's normal to have a really big, mixed bag of emotions now that you have taken the leap, so don't expect too much of yourself too soon, just take things one day at a time.
Do not agree to either meet him or to talk to him on the phone ! He will simply be using any contact as an opportunity to try and persuade or coerce you into going back into his lair !
Any and all communication need to be via email. No texts or calls, and definitely no meeting him !
You really need to block him on your mobile, because you're only going to make things harder on yourself if you don't.
You'll constantly be checking your phone.
You'll be jumping every single time it rings.
You'll panic any time his number comes up.
You'll maybe even feel you have to answer (conditioning in putting him first !), then perhaps even tempted to believe the lies he'll spout....
None of that is in your best interests, is it ? Or in your DC's best interests ? 
So block him. Put yourself and your DC FIRST
You only need to even look at your emails when you feel strong enough (Make sure that you don't get notifications on your phone, change it so you need to 'log in' to see if there are any emails.)
You've done the hardest bit, you've escaped.
Now comes the long slog of keeping strong and of ignoring him, because whatever it is he wants, it's no longer your problem.
It's not up to you to make him 'happy'.
It's not up to you to clean his house.
It's not up to you to pay his bills.
It's not up to you to to cook for him to make sure he's fed.
It's not up to you to wash his clothes so he's got clean ones.
He's an adult. It's all up to him to figure out !
Take time to relax into your new home.
Take time to enjoy spending time with your kids.
Take time to enjoy quiet evenings watching TV or with your friends.
Take time to begin the process of rediscovering who you are, what you like, what you want....................
You've got this !
