Conversation, that's worth anything, should be a mutual interchange. If ideas and feelings aren't exchanged, mutually, whats the point?
Not all "NTs" are any good at it. In fact, most aren't. Being NT doesn't mean you are good at conversation. In general, being "NT" doesn't automatically endear you with anything aside from being.. just like most people (and that.. is boring!)
If you feel someone's talking "at" you, not "with" you.. They probably are. But do remember sometimes people just want to be heard. Heck, they could talk to a wall and get the same result if they were good at pretending...
It's called venting. It shouldn't be the normal mode of interaction, but when someone is really flustered, it's a good thing to get it out. That stuff is toxic bottled up! So let them do so, be compassionate, and offer your tidbits once they calm down. It seems the key is being the calm one until they chill out.
Also, if you're finding yourself constantly being someone's counselor... Refer them to one and stop wasting your time, unless you are trying to building your counseling skills and you find the arrangement constructive for both y'all. I used to have this problem. It was because I focused on people's problems, because I thought I could "fix" or "help" them. They sensed this. Nobody needs fixing unless they specifically ask for help with an issue.
