No. you don't have to say where you are, what you are doing, how you are feeling, what you are thinking.
Every time you do, you give him ammunition, to USE against you. To try and 'fix' you. When I honestly do not think you are broken. Sad, browbeaten and controlled, yes. But not broken.
You a person in your own right. A living, thinking, breathing, feeling person. He does not own you. You are not a robot. He does not have the right to control you, to tell you how you should be thinking, how you should be behaving. To punish you if you do not behave or speak how he wants you too, especially when that behaviour is completely normal.
And it does not have to be confrontational. Don;t give him anything to grab on to. Make it vague and light. Non committal. Don't be forced into making a decision about anything. 'I'll have a think about that' 'I'm not ready to decide that yet' 'I'm still working things out'
I feel that you are still hoping he will see the light and all of a sudden start being nice and normal. Then you can have the husband that you need and deserve. But he won't. And this is why you need space and time. Not to show him you are serious, or teach him a lesson. But for YOU. To clear your head of all the little mind fucks that are confusing you. And to decide for yourself, not us, not him, or even the kids, exactly what kind of a life you want.
What do you want?
