How to get rid of "Ego" I have a Girlfriend that I met few years back. She loves me a lot,she is quite brilliant from her childhood, and now she is working in a big firm. I am working in a smaller firm than her. When we were in college, it seems we will not fight ever, but after we got passed and she got placed we are having a lot of fight. She sometimes says some bad words to me, that i can't handle.But i don't want to fight anymore, but I think I've ego problem. Every time i think not to fight but finally we ended up with big fight. What are the practical measures in Buddhism to get rid of such ego inside one's inside. Thank you.
More than ego, it could be the high level of stress involved in working for a big company. 

In any case, Marananussati meditation would be a good start for both of you. 


  "The disciple who devotes himself to this contemplation of death is
  always vigilant, takes no delight in any form of existence, gives up
  hankering after life, censures evil doing, is free from craving as
  regards the requisites of life, his perception of impermanence becomes
  established, he realizes the painful and soulless nature of existence
  and at the moment of death he is devoid of fear, and remains mindful
  and self-possessed. Finally, if in this present life he fails to
  attain to Nibbana, upon the dissolution of the body he is bound for a
  happy destiny."   -Visuddhimagga


Another reason could be the wanting to control each other. Have a cordial discussion with her and come to a solid understanding of each other's expectations. As long as you two don't exceed that framework, don't try to control each other too much.

Come to an agreement on how to resolve issues. Make a determination with her to always use kind words and wisdom to find a solution rather than disrespectful words and emotional thoughts.
