I am tired....

It happens again......... I can't understand whats the issue...I mean..All someone has to do is follow rules and pass the test.. You are judged against it and thats all that is required....Why can't people understand a simple thing like this..
Ok..Agreed You didn't follow it and failed.. All you need to do is get up and say I have fallen down and not doing something right.. I need to work on it and I will clear my tests.. Its that simple.. But.. no.. my wife has a different attitude.. she feels she is holier than though.. and no one should be failing her, even if she is wrong.. She has all the things at her disposal and yet,she never wants to utilize it and then when she fails, she cries and gets angry.. And then when I tell her its your mistake and you should have done things in a particular way, I am the one who is at fault and not her..Give me a break.. You make mistake and you should be agreeing that its your fault and you will work it out and ensure that you pass.. But no.. Logic works different here.. I make mistake, I fail and Its the examiner at fault and I am wrong to have told her that she failed and she made mistake..
After this ordeal, I am tired and I seriously believe.. I am a fool an idiot who should not be thinking the way and even if someone is wrong, I should be saying no I am wrong and you are right..
I am sure.. I have hit a low point in life.. My wife wants to go back to India, since I have pointed her mistakes that she committed during the driving test today and have told her she had all the resources and she doesnt want to use it.... and she has a negative approach in life something that I personally hate.. All I expect from her is that she should get a license and she should be free and independentl, but I guess, I am wrong and a big fool to be thinking this way and during the argument, I got a reply that she wants to go back home... I guess thats fine.. she can go back and I have told her to inform here parents that she is coming back to india for good and but frankly speaking, I am tired of this threatening and if she goes back... she goes forever.. and thats the bottomline for me.............. I AM TIRED MENTALLY.....
