I did just leave op, I had a small bag of photos and a couple of irreplaceable special items and went with my dc. It was scary, and I lost a lot, but I gained so much more.
If abuse is involved then WA can help you through the process, they will talk to you (phone or email) and discuss all your options, they have access to help from lots of different people, and they really are amazing.
I know the thought is daunting, and it does feel a bit like better the devil you know, I absolutely get it.
There's no pressure and nothing to stop you from contacting WA and discussing your options. One woman who I was in a refuge with was in touch with them regularly for 8 months talking things through and getting the help and confidence to finally leave.
Even if you got in touch and decided against leaving in the end, there's no harm in talking things through at least.
Don't listen to the smug "I would simply never let a man....." posters. It's honestly pathetic how those, allegedly, ever so happy people have to step on others to feel a bit better.
All the best in whatever you decide op 💐
