Learn to discern your partner’s own shady behavior from your own insecurities (and vice-versa). This is hard and will likely require confrontation to get to the bottom of. But in most relationship fights, one person thinks something is completely “normal” and the other thinks it’s really grade-A “fucked up.” It’s often extremely hard to distinguish who is being irrational and insecure and who is being reasonable and merely standing up for themselves. Be patient in rooting out what’s what, and when it’s your big, gnarly insecurity (and sometimes it will be, trust me), be honest about it. Own up to it. And strive to be better.

With that in mind, it shouldn't come as any surprise to learn that research regarding Personality Type and Relationships shows a definite pattern which indicates that successful mates often share the same dominant function, and the same letter preference ("S" or "N") for their information gathering function. Of course, that does not mean that people with different preferences cannot have a happy, successful marriage, it simply indicates that people frequently settle down with individuals who are on their same "wave-length".
