Hello Gem: Welcome to Psych Central. From what you wrote it sounds like you are in an extremely abusive, & potentially dangerous, situation. My personal opinion is you must escape as quickly, & safely, as it can be done both for your own safety as well as for that of your daughters.

If you were in the U.S. I would recommend you reach out to the National Domestic Violence Hotline. But I see you list yourself as being in New Zealand. And, since I'm in the U.S. I'm obviously not going to be familiar with what domestic abuse services may be available to you there. However here are links to 2 services that perhaps may be of some help:

Helpline

Domestic violence – Women's Refuge New Zealand

My best wishes to you & your little girls. Please take care.
