I'm sorry, but you can't change someone who is abusing you. It's just not how it works.
I don't know if it would help to hear this, but it took me nearly a year from realising I was being abused to actually leaving. The day I left I was absolutely distraught and guilt stricken. I felt like the WORST person who had ever lived and that I was terrible for leaving him, and oh maybe if I can stay I can fix things, etc. For safety reasons I planned my escape and left when he was away so he didn't know.
But I left. I almost didn't. But I forced myself to imagine how I would feel if I stayed, what life would be like, and that felt even worse than all the guilt and panic and grief for the relationship I'd hoped for. I realised the only way I could ever have a future where I stood a chance of happiness and safety, I had to leave.
So I just wanted to say I understand why you currently feel unable to leave. It is a process. But if you're able to recognise that you need to leave and why (because he is abusing you and will not change), then you have taken the first step.
The first step is recognising you need to work towards leaving. You don't have to know when. You don't need to know how. But you need that idea planted and growing in your mind.
Information is power. Stay safe, and keep it to yourself, but start gathering information.
I began by searching for answers to all the practical questions I had. I started investigating where I could live and working out a budget. I got a storage locker and slowly and carefully moved my most precious things into it. As time went on I added practical things for my new life.
I got a place on the Freedom Programme. They were a huge source of emotional and practical support to me. The information I learned there about abuse helped me to understand the full extent of what had been happening to me and how wrong it was. It helped me understand how different life could be.
That information gave me strength and confidence that I was doing the right thing. The women there encouraged me by sharing their stories of life since leaving. They reminded me I didn't deserve to live that way and it wasn't my fault.
I allowed myself to imagine what my new life would be like after I left. I dreamt about the beautiful colours I would be able to have in my new home. I imagined not having to walk on eggshells anymore.
I confided in my (female) GP. She listened to me and supported me.
I learnt how to safely cover my tracks. I got a second SIM card so I could have a safe number. I prepared an emergency bag in case things got worse and I had to leave without warning. I kept my passport and other documents safe.
I talked to samaritans and supportive people online. I talked to my GP. I saw a counsellor, who told me it was ok if I wasn't ready to leave yet. That I had to be ready to leave so that I didn't end up going back. That she had confidence I would be able to do it.
And then one day, everything was in place. I had a new home worked out, I had as many belongings ready as I could, I had solved the practical problems I hadn't been sure about, I had a plan for how I would pack up the rest of my stuff and leave while he was away... And I was terrified. I still wanted to believe things would change so I wouldn't have to do it, even though I knew it would never happen.
It took me a couple more months, and then I realised the only thing holding me back was the fear. So I set a date for when I knew he was away and I could move. And I made myself do it.
I won't pretend it was immediately wonderful afterwards. I struggled. It was a shock. I was grieving for the life we should have had. I leant on the places and people who'd provided support. When I wobbled and started talking about going back (mostly from guilt and fear rather than any expectation it would be better if I did) they talked me down. The FP also helped me prepare for how he would respond after I left so I didn't fall for his manipulation.
But things got better after the first two or three months. A weight lifted. I started making plans for happy things in my future (just small things). I saw a counsellor who was trained in abuse and gave me a lot of confidence back. She and the FP helped me feel safe to start to trust other people by teaching me how to identify different styles of abuse early on. (Different abusers adopt different tactics and different styles.)
Things can and will get better for you, but first you have to jump through those flames to get away from him. I know it's tough, and it's ok if it takes you a bit of time to be ready. But you can do it, and your life will get better. So much better than you can imagine right now.
