You don't need the direction he gives you , he has a vested interest in making you feel incapable so you won't leave and he has someone to treat as a punch bag and skivvy so all his "needs" are met. He keeps you scared so you won't step out of line or question him.
You are capable and strong and awesome and for everything else there's mumsnet , we all have times when we question ourselves and our abilities that's when we research and ask questions and use a bit of trial and error.
So what if you make a mistake ?
Imagine how it would be to feel fine with that , to not be scared of someone else's reaction.
Just read a couple of threads on mumsnet which ask for advice about day to day stuff , look at the DIFFERENCES in opinion. You have the right to choose what works for YOU.
On a daily basis , when you're running your home you don't need to be perfect. You have all the people here to ask if you need some direction (people to help you up not pull you down), you can just CHOOSE what works for you.
Now look at opinions on this thread , everyone agrees, you have the right to live a safe and happy life away from this abuse. EVERYONE agrees that what he is doing to you is WRONG , the LAW agrees too , he is not ALLOWED to hurt you.
You CAN do this , you DESERVE a beautiful , peaceful life where you are not being hurt. You are a wonderful CAPABLE woman , walk forward one tiny step at a time.
