Hi Giraffe123,
Thank you for your post and Welcome to the forum. I’m sorry to hear about your situation. You and your children deserve a fresh start- you do not have to disclose where you are moving to if you don’t want to.
You mentioned you are currently going through court- I would suggest seeking legal advice if you are concerned about this. Rights of Women are a voluntary organisation offering free, confidential legal advice on matters including family law, domestic abuse, children and child contact issues. Their Family law advice line can advise around domestic abuse; divorce, finances, cohabitation and property in relationship breakdown; parental responsibility and child arrangements; lesbian parenting. They are available on 0207 251 6577 (Tues-Thurs 7-9pm and Fri 12-2pm).
Take care and keep posting
Best Wishes
Lisa
