Yay, name is back!
Rings are off, and you're back in control of your life. It's not been the way you'd anticipated, but the outcome is the same, if not better. You're not in a refuge, terrified of his next move or looking over your shoulder and panicking about reassuring your girls in the right way. You can now make strong strides forward and focus on your next steps. Not his, yours.
When he called you, was it just to call you names and play the victim or was it to discuss what happens now? Does he know to stay away, or is it all knee-jerk reactions right now? Has he asked about coming to 'talk' or whether he wants to see the girls?
The last thing I want to do is worry you, but be very careful about his interaction with the girls. Yes, he absolutely needs to maintain a relationship with them, but he's shown in the past, time and time again, how everything he does tends to be with a subtext, and I wouldn't put it past him to use them to get to you. My exH actually is a lovely man (just not the H for me) and when we were splitting up, he decided to take our son away for a few days. For whatever crazy reason, he then decided to stay for longer than expected, not answer calls and take their passports - not with the intention of doing anything but just to freak me out a little. He wasn't/isn't a malicious man, just a man who was desperate for things to be different. I wouldn't put it past your crazyass soon-to-be-ex to deliberately try and frighten you in a similar way, just to show he has the upper hand now and then. Like I say, please don't think I'm trying to frighten you, I just want you to be wary.
But that's for another day. For now, hold your head high, talk to people in real life and harness their support, and visualise what your life is going to look and feel like. Maybe I shouldn't admit this but I make mood boards to keep my focussed on the end prize, including beautiful rooms, vases of flowers, a gorgeous chair with a book and a glass of wine, a stunning holiday destination. But I suspect I'm dreadfully sad You're well on your way now and there is no turning back. Go girl!
