You’re really brave to have left so give yourself a big pat on the back. The average DV victim takes 7 attempts so don’t be surprised if he tries to lure you back in. Women’s Aid are fabulous and I’ve found kindred spirits on Twitter. Also, there’s the National Domestic Abuse Helpline.
Have you spoken to the police at all? Do you have or feel that you may need a non-molestation order?
The first two years following separation are times when you’re at a higher risk of danger so please stay safe.
Happy to speak on DM if needed.
