Help to start a new life

My life has not been great lost my father at age of 20 and my mother 2 years ago. My brother lives abroad , we dont really communicate. married at the age of 42 and has not worked out as i would of liked . Im trapped in a house with a extremely difficult man who s only way of communication is by verbal abuse. ive tried staying with friends but is so difficult . All i want to do is save up enough money to walk away. Then maybe i can properly grieve for my mother and live happy with my rescue dog who is terrified with all the shouting
