Read your posts back. What you have shown your daughters is that it's ok for a man to abuse you emotionally for 30 years at which point you have "invested" so much time into the "relationship" that you may as well stay.
You think this asshole will be able to force teenagers to stay with him at his behest? Tell him good luck with that.
You are long overdue breaking free of this abuse. You do not deserve it. Your kids do not deserve it either, but they have been stuck. You have stayed with this man and they have had no option. They will have been hugely damaged.
My "mother" did this to me all my life. Only recently she was so abusive I finally stepped back from her. She is now very old, alone and bitter and to be honest she deserves every moment of that. I'm in therapy for the last 2 years and will be for a lot more. The silent treatment from a parent destroys self worth.
Why did you accept this for so long? What happened to you in your formative years that you didn't feel you deserved better? Or maybe you did feel it was bad but that you couldn't culturally or financially leave? Do some reading about the silent treatment - it is seriously abusive and the effects are long lasting, they go to the core of us as a human being; basically at a young age to have a parent tell you, without needing to say the words, that if you do not behave exactly as they insist, then to them you will cease to exist. A good parent could not possibly do that. Can you imagine turning off your love for your children? Your husband is able to do that. He is damaged and unless he looks into his own behaviour he will not change. So if you want change, and you should, the change is up to you.
I have a feeling that his flouncing off is a self-pity move on his behalf. He will expect you to have learned your lesson and he will come back home with the fullest intent to punish you and your daughter for "causing" this situation. This is a time to stand firm, which will probably be very difficult for you, but very important to show your daughters that it's never to late to reclaim your life, your independence, your self-respect. You wouldn't wish this life on them I'm sure? Show them it's unacceptable.
