Wow. Another new ISTJ here, and oh my gosh I cannot tell you how much of a
cosmic relief reading this post has been. I thought for sure I was the only person who approached life this way. I
totally relate to fishingdude's checklist. I'm 24, never dated, just bought a house, majorly keep to myself and have about a dozen other "items" I feel I need to achieve before I will be stable enough and ready to start branching out and pursuing relationships. The thing is I've always had this nagging thought wondering if there is something majorly wrong with me because I seem to be working life backwards from everyone else I see. I mean I have many good interests/hobbies and am not totally an ugly troll, but I have such a hard time putting effort into pursuing people.
Anyway I just wanted to say thank you to fishingdude and raz in particular for articulating so beautifully exactly what is going on inside me too, and for letting me know I'm not the only one.
I'd also like to say (and I greatly suspect this applies to some of the frequent posters on this thread) that although we ISTJs get deeply tangled up in the cost/benefit analysis of love (boy was that a perfect description by the way) we really do share that which is common to all humans-a deep need to connect intimately with people. That is why this thread was even started - an ISTJ felt a hole deep down and knew it needed to be fixed somehow.
To be honest I think a lot of it has to do with a degree of fear of failure. Success in relationships must be ensured, therefore I will become ultracompetent in all areas I see as foundational to that end i.e. personal growth, financial stability, education etc
before I undertake any risk.
Yes trouble with small talk and all the fluff of social interaction plays a part too, but I believe if we felt safe we would go for it more.
I don't know what the solution is but rest assured I have had all the kings horses and all the kings men working on it for a while now

. Anyway thanks for reading.
