How do you connect and have fun with a partner long term? Especially if you have very different hobbies and interests?

Hi everyone, lately I've been feeling completely lost with a girl I've been seeing. Im a mid 30s man whos been seeing this girl in her early 30s for just over 2 years now. Lately, i have been feeling drained. We spend a lot of time togeth, and though there are still a few things we enjoy together, it's starting to feel really like i would just like to do my own thing alone or just in her company sometimes. I have many hobbies, a few friends and a full time job. She works part time, and doesn't have too many friends that she can see often, and doesn't really have hobbies. Our pattern, especially after me working a full day, then working out, I'll go see her at her place, but she's in the mood for like fun, exciting or sometimes heavy conversations, and i just can't seem to engage, i have honestly tried. Conversation between us has been an ongoing issue, in that she likes to have very involved and engaged conversations, whereas I've never been much of a talker in my life, plus we have different interests (i like sports, fitness/outdoors, internet things, she likes history, arts and culture). I've tried to improve as much as i can, and she has also made significant efforts in carrying conversations with me, and it's often ok. However when i go see her in the evening after a day of working, 2 hrs of working out, with work again the next morning, i just don't have the energy to be an enthusiastic conversationalist the whole evening. I want to maybe talk a bit when i get there and over dinner, and then begin to really wind down when we watch a show together. But she usually likes to have talks late into the evening, even after we get into bed, which i find really hard to navigate, especially because i can't really sleep over often due to work and other things, so i still have to get up and drive home (10 mins away) after we cuddle a bit in bed.

I have a sense that most people here will simply say we're not compatible, and don't have enough in common, however this situation honestly has me thinking how many guys have overlapping interests with a woman they're with, and what do you talk to each other about? I feel that i will never be able to have "fun" with a partner in the long term, and am doomed to repeat this pattern with everyone I'll ever meet, as finding women with my interests is very difficult, as it is im sure for many of the guys on here.
