If what nettletea says resonates then we all 3 have had exposure to men from similar backgrounds.
I think i'm a bit older than nettle, and heaps older than you, so can fortell the future in case you're in any doubt.
This man will NEVER see what he's doing is wrong, because in his culture it simply ISN'T!
I tried for 10 years to have the relationship I thought we could have, but no. Not even baldly pleading to be able to have a life would make my ex think any differently.
Mine had been in London since the late 80s, since he was a teenager, but still, 20 years on he turned from being mildly controlling to being utterly tyrannical when the opportunity presented itself.
Your DD is at risk when with him. He's threatened his own life to get to you, his culture won't stop him here if you don't react. He's threatened you, stated you'll not take his DD, he could easily kill her, and you.
Don't go back. Call the council and explain the situation, get WA to help/advise you here too. Use every resource you can to establish that you are in a seriously dangerous DV relationship and need help to get out.
He's not strong so don't let him intimidate you. This is borne of weakness not strength, so don't allow him access to you or your DD.
Do everything you can to have him sent as far away from the pair of you.
Does he have a right to be here? What is his immigration status?
