You can do this. It isn’t going to be easy. I wish I could say it will be, but that is unlikely – abusers don’t like letting us go, so I would go into it expecting him to act badly. But you can do it. Reach out for all the support you can get. Keep writing here. Call women’s aid to get advice about what to do next. They will be able to direct you towards the legal help you will need to move forward. And keep your contact with your abuser to the absolute minimum possible in order to protect your mental health. Things will get better.
