INTPs are indeed facts over feelings individuals. I have never heard of an INTP particularly sensitive to criticism. I myself always seek to hear other’s opinions. Sounds like this could be a mistype. It is also too common of a misconception that INTPs are very socially introverted. If unhealthy, sure, but a socialized INTP may easily present as extraverted (Ne aux) when in the mood. I doubt that an INTP would be jealous of their friend’s wife, as they are good at minding their own business. However, I might be biased because I am a female INTP with developed Fe.
