It sounds like you have all been through a lot and the toxic relationship may be over but the cleaning up process may take some time (not just the house but airing your thought and feelings). Have you thought about asking family or friends and your children to help with the clean up of the house?
Also may help for you to talk to someone about support and help with moving forwards (I have to do the same myself as my situation is not amicable).
I hope things improve for you and everyone else that is facing difficult times in this group, however I’m sure in time they will improve for us all in time with good days and bad inbetween.
My father was an alcoholic; wife beater and had loads of women on the go. He was a good father, had a good job but he was a nasty piece of work . He provided for us but he tortured my beautiful mother and tried to break her . None of my siblings are alcoholics; wife beater and rarely drink and we are all parents and have children .once the children are removed from that toxic environment they will be happy and thrive. Good riddance to rubbish is my motto . Good luck xx
