Since you're a "Dr.", I would presume, you're pretty good in solving issues related to engineering? business? etc.? How about resolving love related issues then? You've kept saying that you're a selfish person. However, I would really like to know, are you being selfish enough in fighting for the opportunity in your own relationship against your parents?

Based on the story of which you have put together, I would say, you're a pretty good fighter, in fighting off the odds during your studies, and in work environment while trying to meet your dad's expectation all the time.
You have tasted so much of success, while losing your sense of what failures are meant in life. In other words, your "face" is more important than anything else in the world, and that sacrifices your relationship with your girlfriend.

It's all about YOU! YOU! and YOU!.. but you did not even fight for your loved ones, be it against your dad's advice, expectation nor your own priorities throughout your life. All I read was RM1,500, RM100,000, etc. what else? if figures are meant so much to you, might as well let her alone all together, and you can go with your own ways of looking for more figures?

You kept saying that your dad's expectation, dad's businessmen, dad's advice, etc. Don't you have your own expectation, priorities, advice, etc. in a relationship? To be honest, your dad is not the person who will marry your girlfriend, rather yourself. It's about YOU! YOU! and YOU! Therefore, how ironic it is, when you have admitted that you're a selfish person, but never got selfish in this sense? In a way, I believe you will fight for your relationship against the odds when you are being selfish in that sense.

If you think your "Dr.","Business achievements, Titles" are difficult to achieve, try to put yourself in your girlfriend's shoes. 5% of your total time, 5 mins in a week worth of Skype communication and 8 years worth of her life staying loyal to you? was that difficult for her too?

Oh, speaking of you got mad at her about the intention of "testing" you. Apparently, you've studied so much of engineering dummies for 101 and business dummies for 101, you haven't really got yourself a book, relationship dummies for 101? ( not the real book titles ), but you can perform some "research" on what actually the definition of "make love" meant in a relationship

Seriously, if you are not even able to get your priorities straight in your OWN life, how can you actually give out talks to others by attending seminars, forums, etc. to share your opinions and comments in achieving the success of your life? by sacrificing the relationship of yours? is that how your followers should achieve as well?

I would like to apologize as I do not meant it in a harsh way, but if you can accept the harsh comments from your dad in related that you're not a good businessman despite had a "PhD", then, I am very sure of my comments and opinions are not that harsh after all
