Actually, in my experience I found that it's the INTJs who would be most understanding if you made a decision based on personal values or emotions. Because they can separate between logic and emotion, they know that it's possible for emotions to overrule logic, especially when it comes to personal principles. The NFJs kind of disagree strongly and try to impose their values onto you, and I think it's because their logic is their emotions or that the two are entangled together or something like that. Not all of them of course, it's just the experience with NTJs in that aspect has been more consistent for me than the one with NFJs. NFJs tend to question those very same emotions you are trying to convey. Personally, I find that worse because emotions and sentiments are privy to the person. (I feel like I am going to offend someone with this, I'm sorry).
INTJs might not cater to that emotion or agree with you on the principle but will acknowledge it and leave you alone. I think INTJs are capable of picking up on subtitles like body language and facial expressions. What they won't do is draw conclusions from just that or infer, and so they wait for you to articulate it explicitly so that there is no room for misjudgment.
The awkwardness is on your part. You need to learn how to communicate your feelings clearly. It's not easy, I can understand that, but it's necessary, nobody is ever going to know what's on your mind or in your heart better than you do.
