How intense are your feelings?

My INTP boyfriend says it's "crazy" how badly he wants to move to be with me. He describes it as "intense."

I don't believe INTPs are the stereotypical "robot" at all; not one bit. But what does it mean that his feelings are "so intense"? He must really like me then, huh? I guess I just don't understand why he wants to be with me so badly.
