Steps to take next

[Teafor3plz]

What steps do I take to prepare for splitting up. Partner is always speaking to me in an awful tone, thinks every comments i make is wrong, only talks down to me. Tells me i have no friends and says he has loads "why is that, maybe you arent nice". I work FT, look after three kids, homework, housework. He is free to come and go as he pleases, and he does, including weekends away. How do I protect myself as he says he will take the kids as much as he wants even though he does nothing with them as he prefers to socialise or work

Are you in rented or do you own ?
If rented are you both on the tenancy? Mortgaged, is it in both names?
If you are the sole tenant you can tell him to leave.
I’d say priorities are getting money together ( as much as you can) Finding housing if you have to move out.
Get together all your paperwork, passports, prod of ID etc. If you can leave these with a friend for safe keeping so he cannot destroy them.
If you or the children are in danger call Womens Aid for advice on how to leave immediately.
If he threatens or attacks you call 999 and request immediate assistance.
Men say a lot of things to get you to stay and in their control. One is they’ll deprive you of the children. My ex threatened all sorts, including lying where I worked which probably would have got me fired. In reality I left and afaik he did nothing to find me.
Good luck.

Hes just completely changed from the man he was. I can actually see he hates me, although im starting to feel the same about him. We had another argument today, where I was again told so many hurtful things. His mother is a horrendous woman, I dont want her near my kids due to her alcoholic partner and the things she has said to me over the years. He says he will live with her and she will have them as much as him. That really scares me, to the point id rather stay in this non existant relationship so i can make sure they are ok and safe with me. My kids are my whole world. I feel so so sad
He wouldnt take the house I dont think, as he couldnt afford it. I could as my parents would help me

Legal advice maybe? He’ll start to threaten all sorts to beat you down. They find the thing you’re sensitive about, or the thing that scares you and home in on that. He is emotionally abusive to you and it’s really bad for your children to grow up heating the things he says, very damaging.
Get some legal advice. Can you talk to your parents about financial support?
Write down every bit of evidence you have —- when he’s abused you, what he’s said. Whether the children were present, or could hear. Tell the solicitor about MIL and the fact that an alcoholic partner is neither safe or good for your children.
You can do this. Get yourself and your children the life you deserve.
