You know, one of the things I love about this pair is that how easy and natural to be honest with one another. I don't hesitate to tell my INTJ something because he won't intentionally misunderstand me or ignore it. He is curious about what is really going on so he can help to find a solution together. He naturally shares his mind with me, it is so refreshing to see how transparent his mind and heart is. I have no doubts; he loves me, he wants me. If not, he wouldn't spend a second on me. I don't share my views with most people because most people fundamentally don't share similar vision like I do but he does. We might have different views but we look at things with similar humanitarian goals and with as objective as possible explication.
Probably hormones play a huge role but I think it is pretty much of a big deal that he is the one and only person I don't get tired of being around and don't feel drained by spending days & nights being with him without much alone time. We can be alone together, and we are one together. How fantastic is that!
