Hello Lonely, and a warm welcome to the site and thanks for posting your comment in difficult circumstances.
Being un-kind can still, unfortunately, be another way of abusing you and the children and it's called emotional abuse, still detrimental in not only how you react but also as how you are viewed in his opinion and it's very uncomfortable for all of you.
All of this disrespect towards you and the children does build up, making you frightened to even sneeze at a time when he may be involved in doing something personal and doesn't want any disturbances.
I'm so sorry that you and the kids are put under this pressure, that shouldn't necessarily be the case.
Can I ask you a question or two and please only answer if you want to, it just gives us a little more understanding of the situation you're trying to cope with, and I do apologise.
Are you receiving any Centrelink payments and renting or purchasing a house, I only ask this because it's a way that we may be able to help you.
Does your husband work?
You won't be alone, so please us help you.
