Their dominant Ne is nothing to look down on and I absolutely admire their outgoing-ness and spontaneity and brains.
But my other best friend is ENTP so I might be a bit biased there. Like, is it a romantic, sexual, queerplatonic, intellectual etc. Most modern type practitioners recommend the INTP-INFJ combination for various theoretical reasons, and in practice it is observed to work very well.
Better yet, find your partner’s type and see how he or she is. You go about your quest for love as you would go about your quest for anything else in life: with careful thought and logical execution.
You crave a strong, deep relationship and rely on your trusty logic and intellect to know that you are keeping your partner satisfied both physically and emotionally.

But in fact, Rational-Idealist pairings have an even higher satisfaction rate, namely 65%.
