I am certain that we all happen to say it to peoples around us in relations,"You don't understand". There are times when its really hard to prove oneself to others, even to one we love and with them for a long time. The only part matters that what they mean to us.
We have to take initiative even though we know its difficult to make someone understand something which is true for us but to them its a vague action. Even for simple things the situation becomes so tough that we give up and say you don't understand and move ahead but its a decision that we make either accepting the defiance or losing the patience to take the pain to make them believe in our thoughts.
It's also a matter that to them our step or activity is not a true thing to take place but not everyone is perfect. So one just need to put a point that even his actions and steps are wrong but he/she wants the other person to be on his side and see things through his/her perspective which will let them understand the situation in a better way. None of us like to be wrong but we fail to make an attempt to make that understandable to the persons we love.
So, do take initiative to explain yourself even you know he/she wont understand.
