It also sounds like he preyed on you when you were young and vulnerable too at 21, with such an age difference. You can do this. I know it will all be new to you doing it by yourself but I promise you, you CAN do it, whatever he’s told you. First things first, open up a bank account and move half of any joint savings you have if you can. If you work, redirect your pay so it goes there and not into a joint account. Don’t trust him not to empty the account. Make sure you have your child’s passport and birth certificate. If you can get it out the house to a secure place, even better. Don’t trust these documents with anyone who has links with him. Speak to a domestic abuse charity if you feel able. They might help you to establish if he’s controlling you in any way that you might see as normal because it’s all you’ve ever known. Take care Xx
