My dad is an ISTJ. He keeps his feelings tucked very securely away. I think part of that has to do with a reaction to his childhood environment, but it makes it hard to be close to him, even though I am assured that he loves me and is proud of me, and I love him. With a parent-child relationship, it is fine. If it were a romantic relationship, I think after awhile it would be very frustrating and unfufilling, unless I saw that the other person was aware of the problem and was making some efforts to meet me in the middle.
I have also been in a 5 year relationship with an ESTJ. In both cases, I appreciated the STJ sense of practical day to day stuff. They were good at filling in details of my big picture ideas (it wouldn't occur to me before organizing a big music event to check that we had extra extension cords etc, even though once it was pointed out to me, I would understand the human impact of not having what we needed and make great efforts in the future. I just wouldn't see it myself.). I liked the way the notice the things in their environment that I am pretty oblivious to.
In a relationship, I can see the lack of communication (particular when the INFJ senses something is truly wrong and you are responding by withdrawing) being the ultimate issue. Therefore, if you are dealing with something, you could alleviate problems on both ends greatly by being willing to articulate what you can, and offer some ideas to the INFJ for what would be helpful. Otherwise they will fill in the blanks with their best guesses (which can by annoying inaccurate), or start hovering in a frustrating, insecure sort of way, because they have a huge aversion to emotional surprises and don't know if it's a problem between you to be pursued, or if it is quite unrelated (in which case they need to be given a way to be the most helpful and loving to you). They tend to seek someone out when they are unhappy, and so when you don't, it can be interpreted that you don't trust them, or that you don't consider them to be the person you'd turn to if they had to pick someone. That can be hard for them to deal with unless they have enough context to realize that your process for solving problems is extremely different.
Your INFJ may assume that since you don't seem upset and since you sound definite about things, that you are not requesting their help. They may even feel that you don't need them, especially if you are very competent and don't choose to turn to them to fill in the areas where you may need their skills. They need to know why they are needed by you, so that they can feel effective in supplying what you value. They also may not realize that Te sounds definite, but may actually be requesting advice or a mirror to check their reasoning, just as Fe users often don't realize that statements they make may be taken as definitive statements, rather than running something by for someone they trust to check over. I remember my ESTJ getting rather frustrated at me after he had tossed around several possibilities for what to do with the inheritance from his parents, because he thought it was obvious he was requesting my opinion, while I thought I was being respectful in not offering one when he had clearly decided what was right to do and we were not sharing money!
Resolving conflict is one of the hugest communication issues I have found in interacting with STJs. They seem to feel that as long as it is not being talked about and there are no external signs of strife, all is well. This is a huge mistake, especially with INFJs. The issue will not go away until it is laid to rest. They may even need to revisit things several times, which may be frustrating to you. Just realize that it is not about accusing you, but rather that there is a problem that they need your help resolving and that you are doing a huge service in getting them to the resolving stage, simply by listening without offering opinions and solutions until they are ready. They may comply with your preferred method for a time, but resentment will build and larger parts of their inner self will be walled off to you. Even if you don't feel sure of your way, opening up the topic for discussion, rather than avoiding it or just helping out extra around the house will win you trust and points like you wouldn't believe. Asking question that get your INFJ to talk more about what's bothering them will not only burn out their frustration sooner, but will also give you more information and context to work with. Stifling their venting is like adding gasoline to a fire that they are already distressed about and embarrassed of.
The INFJ Common Issues thread may cover some others - I'm not sure. Sounds like you have a pretty good handle on things.
