Went and found the book. The author actually calls them "sensory modes" - a preference to one kind of sensory information, and you'll usually use language that corresponds to your preferred mode/input. This book lists:
Seems like I mixed this up with another book about multiple intelligences or teaching pedagogue because there's no list of traits to identify yourself in this book. Oops.
I'm going to guess that "I get what you're saying" leans to kinesthetic (touch).
(This is a newer version of the book that I'm referencing, btw. I recommend it.)
I recommend that you get https://www.amazon.com/Gentle-Art-Verbal-Self-Defense-Work/dp/0735200890 and read it. It will help with this, and it also offers some useful pointers for communicating, generally. Very useful for a litigator. I also recommend https://www.amazon.com/Deposition-Handbook-Revised-5th/dp/1941007309/ref=sr_1_2?keywords=the+deposition+handbook&qid=1555794825&s=books&sr=1-2 which has only a small section on this but is invaluable as a handbook.

I suggest leveling whenever this happens. Express your objection, and the reason for it, and ask for an apology. Watch closely the reaction. If the person is speaking in good faith, talk it out. You are a professional advocate. They are a laymen. You will win; if by some chance you don't work out why, and adjust your technique accordingly. If they repent, forgive them. If at anytime they go rogue - resort to verbal attack, outright insult, false reasoning, etc - then stop talking it out and hammer them like you would an opponent who tried that in open court. Call them out on the insufficiency of their defense, state plainly the wrongdoing they have committed, and impose whatever sanctions are within your power to have imposed. Don't be ashamed to have your boyfriend pitch in if he's the one with more direct influence, which, in his home or at his family's appointment, he probably is.

Also, if you haven't passed the bar yet, then don't take being mistaken for a paralegal as an insult. You don't yet have a license that sets you apart from them and there are paralegals who differ from attorneys only in that they are unlicensed. Those would take a similar offense to you objecting to be compared to them.
