Hi Kim32,
I came on here to look for some support for my similar situation. I’m not experiencing the domestic abuse but a lot of other similar issues with my husband. If you want to leave you would be able to get support from women’s aid or a local womens support centre. They can help you to leave in a planned and safe way but without him knowing what you’re doing. Hope you find the support that you need now that you’ve made the decision to leave.
