@Shanamie,
Myself I am reclusive in physical life and have been for the past decade+. My wife is a PhD and like myself she has little time for people or society hence she is as reclusive as myself .... the whole COVID isolation thing, that is just normal for us anyway.
Even the most ebullient of N Europeans are by most standards, quiet and seemingly unemotional and aloof.
However, truly introverted people do not in my experience or that of my wife, make idle gossip .... My wife and I dislike being away from each other, we are much like a single entity by choice .... So we sit about 1 mtr apart, all day, every day .... Yet we'll go hours without a word. When we do talk it is always about academic subjects; psychology, philosophy, physics (excuse my alliteration) and so forth. Neither of us can abide noise or people in the house other than us two and our little dog.
Our two adult children live in other countries and my wife talks to them on the internet very occasionally when they make contact .... That contact is usually work related as they are also PhD's .... Myself I will at most ask her to say hello to them.
So my point would be that you seem to have a need to 'talk', whilst really introverted people do not do that. Rather, they are innately quiet.
A little further advice, if the gentleman has made his 30's with just one previous g/f some years ago, then you need to ask yourself why that is and be somewhat careful.
