My sister is dating a guy that so far I've typed as an ESTx. She is an INFP and I am trying to offer advice on what to expect from him behaviorally. (Trying to shield her from being hurt).
He is outgoing, a straight shooter, and very protective of her. He is pouring on the compliments and affections very quickly. (She is falling for it while I'm not so sure I trust him yet.)
Anyway, I see that ESTPs typically go for short term relationships while the ESTJs go for long term relationships. What other differences can you find between these two types as far as relationships, loyalty and any other traits.
Finally, are INFPs and ESTx compatible?
