Hiya.
I recently escaped a shorter marriage that had become abusive like yours, in the way strangers described it as abusive but I wanted to make excuses that it wasn’t.
I promise you, your reclusiveness will be at least in part due to the abuse you are suffering, that you won’t be able to acknowledge properly until you aren’t in the middle of it.
How old is your son?
Mine is little, and it’s been much easier on him because he doesn’t really understand we’re divorced but he gets happy time with mummy and happy time with daddy. It took a while to get to this point, but this time a year ago I was where you are.
I promise you, living in this tense environment IS damaging your son more than you taking the steps to protect him would.
Whose name is on the deeds and the mortgage? We can help you come through the other side. It won’t be easy in the short term, you know that, and the scariness of the change is what’s stopping you doing it.
But life can be better than this. You don’t deserve to spend the rest of it like this, no matter how old and scared you think you are. Do it for your son.
