a few points -
If you leave your children with this sorry excuse for a man chances are the abuse will pass over to them. Even if he is not physically hurting them i think you know by his ability to tell the entire town a pack of lies about you that he will subject your children with a bombardment of ' mummy didnt love you enough to stay' mummy never wanted you enough' its mummy's fault she left you and now i am having to cope' is this really how you want your children to be raised?
What sort of values to you think they will be passed down by a man who feels it is acceptable to torture and batter his wife. to hurl abuse at her in front of his own kids?
As for the practicality's of it. And im sorry if this sounds a bit harsh but i think you need a kick up the arse into action so to speak.... you need to take matters in to your own hands.
You have came on here and managed to ask good questions and look for advice.
Now what you need to do is go on to google and start looking for local solicitors who offer legal aid in your area.
You need to go onto your councils website and find out there policy on emergency housing.
You also know how much you earn. go on to a benefit checker website. this will tell you how much help you are entitled to. If it requires housing costs guess from what is currently advertised for rent in the local paper or estate agents.
Your Children are under 5 so you will be entitled to free childcare of 15 hours at nursery age, and this is set to rise.
If you dont think you can cope with working right now as your childcare is unstable then that is also fine. As a single parent you will be entitled to Income support until the youngest is 5.
You need to find somewhere safe in the house and start collecting the following into a bag -
Passports, Marridge certificates, Birth certificates, copy of bank statements, saving investments, bill providers. any spare money you can get hold of.- if you cant manage this then try over the next few weeks to buy tesco vouchers £5 at a time(lie and say you are saving up for christmas) Change of clothes for you and the kids, Spare mobile charger, Phone book, medication or prescriptions.
In other words you need to start taking control and planning and plotting.
I know, i have been there. through womens aid, then having to turn up and the council, emergency housing, and having to cope with no support.
You can do this. The reason why you dont think that you can is that this is what you have been conditioned to think so that he remains in control.
Being on your own can seem scary... But it is also empowering, thrilling and can make us realise that we are more capable than what we thought because quite simply we have to be.
Ask yourself honestly, if a female friend was going through this and told you she was going to leave but not take her kids what would you think?
