I am reading this with great interest @Twelftytwo, what you are describing absolutely mirrors my relationship with my partner, although I am the male party and the Introvert, preferring to spend quiet time, in quiet places, doing quiet things with quiet people and in wide open spaces, surrounded by green and living things, away from crowds, noise, 'busyness' and built up areas. Hence the reason I chose my house very carefully, a mile up a single track road, no neighbours, surrounded by fields and greenery. My partner, by contrast, lives in a city and, every weekend, when I travel to visit her, I feel hemmed in, suffocated and like an animal in a cage! Add in the fact that she is very, very talkative and 'talks over' me much of the time, tries to talk to me with the television on in the background, which I find rude and distracting, we spend much of each weekend around her family and, by Sunday evening, I am 'peopled out' and itching to get home to my own home to decompress and have some solitude! The talking is non stop - twice, recently, during our evening telephone calls I have left my phone, on speaker, in my living room, gone into the kitchen to make a cup of tea, come back 5 minutes later, and she is still talking, unaware that I have been absent (yes, I know it was rude of me, but frustration over ruled good manners!).
I am not suggesting, for one moment, that you are this talkative OP, but for introverts, incessant talking is draining, and yet, in the right company, I can open up and talk for hours about current affairs, the news, politics, history, science, horticulture, botany, birds, animals, insects and all the things which I enjoy, but if people start talking about sport, television, or just general small talkI am alk at sea and lost!
The short answer is that, speaking personally, it is not working for me and I am reevaluating my relationship - not least because it is not fair on my partner to be with an introverted personality and I know that she finds my general quietness frustrating.
Sorry, this has probably not been very helpful to you...
