Hi elle. Welcome to the board. As Radcliff said, it is good that you are reaching out for help and support. What you describe here is domestic violence.
I want to link you to our safety plan here:
SAFETY FIRST
DOMESTIC VIOLENCE SAFTY PLAN Please read through it and fill it out as it can help you think things through and it is important that you have a plan. If you need help filling it out, we can help with that as well.
Can you tell us more about what sort of support system you have, other than here that is?
