What would you encourage your SO to do, if you could clearly see that they have very different passions and hobbies than their current career path?

Would you encourage them to stop what they are doing and even to drop out of their current college, in order to pursue their true passion, even if it may not make as much money? Or would you encourage them to ignore their passion in order to pursue their current career even more, in the hope that this could eventually grow into their new passion? Or would you simply not say anything and let them choose what to do for themselves.

TL;DR I am in this specific situation and I feel as if my girlfriend's advice for me to drop architecture in order to pursue computer science is not quite the advice I was hoping for... Is she right? Is my plan too complicated to work? Am I wasting my time by doing something I don't like, but that I am very capable of doing, just to make money, in order to support my hobby?

This question stems from my personal life. I am currently 1 year away from graduating architecture school and I can say honestly that I didn't like this one bit since the beginning. I made a conscious decision 5 years ago to pursue architecture because I have been told that you can make a lot of money from it. My true passion are computers and technology and I swore that I will never forget about my passion no matter what I do.

In the past years I learned a lot about servers and I have built one in my home. I find something exciting to learn about technology every day. Everyone who asks me about architecture will very quickly realize that it is not my true passion. And my girlfriend did as well. But she is encouraging me, and has been for the past 3 years, to ditch architecture school and pursue what makes me happy.
