Romantic relationships
In love, INTJs are loyal, sincere and deeply committed — once you choose a partner, you're in it for the long haul. You don't do casual well; you'd rather build something real and lasting with someone who shares your values and your vision.
The challenge is that you express love through acts and plans rather than words. Your partner may not see how much you care unless you learn to say it. When you trust someone enough to be vulnerable, that reserved exterior gives way to a surprisingly warm and devoted romantic.
