ENTJs can sometimes be intimidating. Sounds like you want to be more relaxed around him, and not have to worry about how you feel or think about what they say. ENTJs often tend to feel they are right and assert their opinions as facts. They often forget to consider the other side. The best thing is the see their responses as merely a reflection of how they think, not as truths about the world. They often give the impression they know it all and expect others to defer to their judgment. For me, I don't argue with them, but I've learned to not allow myself to fall as easily into the trap of thinking they are right or that their views are final or absolute. Don't see what they say, how they think or behave as something to contest or fight or compete with. Easier to see it as just their way. In other words, don't take their word for it that their thoughts, words, or feelings are more important then they assert. In other words, don't take them or their views as seriously as they do.
