Don’t believe his lies about the courts taking the kids from you. He’s saying that to manipulate you so he gets what he wants. They would never take the kids away from the main carer for no good reason. He’s not a nice person and this has been brewing for years.
Speak to a lawyer as soon as possible. Now. Today. Get an appointment for ASAP. Before he starts to hide assets you are owed half of and pretend he has less than he does.
Can you secretly start photographing his bank statements, savings accounts etc, his P60, any financial info at all?
If you are entitled to half of stuff then that means half the house. Without a job you will be unable to buy him out of his half of the house so you’d own it all, as you need a job to get a mortgage.
So the courts may either let you stay in it with the kids till they are bigger, or the house will be sold and you both go your separate ways with your separate money to buy your own places.
Think about if that’s enough to get a place in the area you want. Near a good school etc.
Start looking for part time work. Do you have any work experience? If so perhaps that is the starting point as you’re more likely to get a job in day a supermarket if you’ve worked in them before and are happy to update your skills.
Honestly, it’s easy for me to stay, but from the court action before it seems like this has been in the post for a while. You just delayed the inevitable by not leaving then. Please seek legal advice and go this time. It’s daunting I know but you can do this. For yourself and then. Don’t believe him when he spits his lies. Things will not get better while you are together. He’s not nice. You deserve better.
