Thoughts are with you during his difficult time. A roller-coaster that has many twists and turns but eventually will slow down and you will feel different again.
Everything I've read on this board sounds very in the right and safe things for you and your children, I'm so glad you have been working with professionals who understand the vital importance these matters have.
Try not to think too much about the future or what has been happening in relation to the XABF as he has his own journey that only he can take, as you do too, with taking time to relax and enjoy some time to yourself/with children as this nightmare begins to fade into this manageable reality you are creating.
Well done for all the good news (it really is!) keep yourself protected with a lawyer and continue working with those that have your families best interests firmly in sight. Wishing you a calm weekend
