It doesn't matter what he says, @karisa282 - the police will understand that you're not the abusive liar... but that he is. Please listen to everyone on this post, who are all very concerned about not only your safety - but your children's too!
A few years ago, my daughter had a psychotic break with reality and decided that she wanted to, essentially, get rid of the younger sibling she never really wanted and punish me for not terminating the pregnancy, like she'd told me too. At the time I was pregnant, not only was she 8 years old, but it was very much planned. She wasn't happy about a lot of things, didn't want my then-partner on the scene (not her biological father, but we'd been together since before she could even remember... but never lived together. Ever. Which is important as to the actual why!) and hated the possibility of having to share me even more than she already had to. My career was/is demanding, she liked being the absolute centre of attention, which - in hindsight - I didn't deal with very well (as in, I tried to explain to her that she is but a very small cog in a very big wheel), and neither did the schools. When she had the psychotic break, she was 19 and her younger sibling was 10. In 2016, she decided that my having been single for 6 years because she ordered me not to ever date again, wasn't good enough. So she rang the police and told them that I'd assaulted her. Lied through her teeth to them, to have me arrested (which yes; they had to do whilst they investigated her claims - the laws had recently changed concerning domestic abuse/violence, you see, which she didn't know, so these very apologetic police officers who'd responded to her 999 call and found me and her brother not only still in pyjamas because we were both sick at the time, but her in gleeful hysterics, took me in to the cells) and her 10 year old brother taken into care. That was her plan. It happened. I spent 7 hours sat in those cells, worried sick that I would never see my son again because of my daughter's lies. And I hadn't actually done anything to deserve it. Luckily, a year prior she'd warned me of what she was intermittently planning on doing and I'd the foresight to DM a friend about it. I could prove that she'd planned it out in great detail - and I gave the police officer who was investigating my alleged offences, full access to that social media account, to do a deep dive into the messages (which was embarrassing as the friend and I were discussing things like her struggles to breastfeed and things like that, and the officer was male). During the interview where I broke down and outlined all of the abuse which she'd dealt out to me/her brother, he kept asking me if I was frightened of her. He knew, because he had years of experience dealing with DV and abuse cases, that I wasn't lying, that there was something going very wrong with my daughter's MH - because he'd undoubtedly found my DMs to the friend in which I'd expressed my anxieties concerning her shifts in personality and behaviour (which, at the time, we'd all been putting down to the lad she was seeing - who ended up running away to the literal opposite end of the UK to escape her!) - and that I was genuinely afraid both of and for her.
I was released without any charges being pressed against me - which, due to the nature of her allegations, would have been out of her hands completely because of the shift in the laws regarding DV and abuse! - and she was invited to a full psychological evaluation. Which was great, because she received a proper diagnosis, medicated, and didn't end up in prison herself. My son... was never taken into the care system, and although we were assessed by Children's Services, because of his age and her lies - we welcomed it. At that point, I was still terrified of losing both of my children...
The police are trained to pick up on nuances of behaviour - tells, if you like - when they speak to people in situations like yours/mine/thousands of others. And they know that anyone can be abusive in a relationship (in your case, it's your husband, in mine it's my daughter, in Joe Bloggs from down the road's, it's his wife...), for any number of reasons, and they deal accordingly. They will help you! Please believe me when I tell you this. You have to protect your children by protecting yourself. If he takes them to Iraq, you may never see them again. If you stay with him, and he kills you, then they will never see their mother again.
Your father is wrong, by the way. He is victim-shaming, which a lot of people do. Think of the rape survivors who are too afraid to take their rapists to court because from the very start everyone judges what they were wearing, if they accepted a drink from him, if they did X, Y, Z to encourage him... That's very similar to what your parents are telling you now. Nothing that you have done, warrants what your husband is doing to you. My daughter also recorded me - shouting up the stairs at her to tidy her room, or telling her that I was tired of always having to pick up after her... The police officer who was investigating me, obviously spoke to her and told her (my parents were both present) that she was exhibiting signs of coercive control and that she could be prosecuted for it. That she could go to prison if I mentioned during my interview that she'd been recording me (which I didn't because I didn't know at the time - my parents were the ones to tell me!). Now my abuser is/was mentally unwell - but yours... actually, I'm more inclined to suspect that he's just abusive as a general, all-round individual. Which is worse. Because he is making the choice to treat you, the mother of his children, like this. And it's you who are terrified of facing the consequences of his choice.
Please, from the bottom of my heart, OP, leave him. He will never change, he will wear you down until you snap and possibly end up doing something daft - and it's your children who will ultimately suffer the consequences, without their mum around to protect them.
