My spouse never understands me and we keep fighting. What should I do before the marriage breaks down?
Stop explaining, start changing yourself
When a partner has not understood after being told, shouting 10 or 200 times will not change them. Stop putting your effort into making them understand and put it into changing yourself.
If they do not understand once, they will never understand, so stop putting your effort into explaining, and at that time start putting your effort into changing yourself.
