Oh sweetie, I'm so sorry!
You need to concentrate on your safety plan, and if that involves keeping your head down, having sex etc, well, whatever it takes for now. Please don't feel bad about that.
I worked in dv services for eight years. We had amazing, strong, educated people, doctors, teachers, judges....anyone can be affected by abuse. And anyone would try and make it work for the sake of a child. You would not get laughed out of a dv group, and I think that you need to contact your local dv support service now. Get some support, make a plan.
I don't know the set up with you, in the uk anyone escaping dv can access a safe house and get help with rehoming etc.
Maybe have a look and see whats about in your area?
In the meantime, if you can, it's a good idea to get some money stored up somewhere. Know where your passport is, medical card, car keys....maybe start taking a few items to work with you, start filling a bag there, some things for your child too, eg favourite toy, book etc.
I know it is exhausting walking on eggshells, tiptoeing around trying not to agitate anything...look after yourself as best you can.
Big big hugs and thoughts going your way.
