INTP and INFJ are a true golden pair, I think they work best as friends and this would prob be the best friend an INFJ could really ever have outside of another INFJ. But thats not what this is about! so lets have it.
INTPs just dont care. they just dont care. Now INTPs will say they care and get upset when they are told they dont and that they are heartless. But the truth of this is that INTPs do in fact care, but they care about themselves MORE. this is never a 2 way street with them, when it comes to love they just dont get it and never will. They are fine to go on a date and are entertaining but real love? in dont think so INTPs believe that love is a choice and its a rational thing. If you love them but they dont understand WHY you love them than to them YOU DONT love them. It doesnt make sense. they will analyse the hell out of it when its really simple. Love means one person loves the other MORE than they love them selves. Thats it, I am not sure an INTP can ever truly say this about another person. They love yes, but how much? how far? its deep yes? but not deep enough to do anything about. INTP will never fight for love, A love relationship for them is all about meeting half way. which is the same as saying Half ass. INFJs know what true love is. its not half of anything, its full and complete and INFJ love, I mean damn it does not get better than that. But an INTP would not see it that way, they would toss it aside. its just one of million possible loves all different all special (which is the same as saying none are special) in the end they are always right, you have too put things in there logic language, if they are happy you should be too, if you are not, dont count on them to save you. but you better pull them out of there loops of sadness! and moods. An INTP would/could not save anyone, not for a lack of wanting too they just wont. Its all about them, making them safe making them secure, give them space, dont expect or ask anything of them, and you wont be let down. I just dont see how this is good for the INFJ. Its great for the INTP in fact its there best option. but its a one way ticket.
If there was one thing I would wish INTPs would learn is that, when you get that feeling that cant live without someone (and yes they get that) I wish they would get off there ass and run right into the dragons mouth and get that person they love! fight for it or die trying! man if they could do that just a few times in there life they would be amazing.
but than again if they did they would not be an INTP.
