Gladly - this is a topic near and dear to my heart.
I've always been - I wouldn't say a loner - but I've always enjoyed periods of solitude. My wife is the opposite...she's the sort that always wants someone around. We butted heads bigtime over this when we got married, until we found a compromise.
The compromise is basically that 1) my time is not my own, but 2) we could agree on some time that was my own.
In the first several years of the marriage, it was time to write. I got it in my head a few months after we got married that I wanted to write a novel. At first it was like "I'm going to go write all night, every night", but that caused massive friction. The problem with writing something like a novel is that you can't just play around for half an hour...but we finally settled on a schedule where I could have dedicated time to write three nights a week.
This kept on for several years. Then we had our first kid. And I switched over to a new job with a large writing component. I started to get severe burnout, but kept what I could of the schedule just for that coveted solitude.
Then, around the time our second was born last May, I decided I need to change things up. I'd been having this crazy need to do something with my hands. No room for a project car, and besides, that's a terrible idea with little kids around. So I thought I'd take up modeling. Spent a few weeks reorganizing the garage, and then I was off.
My schedule now is basically...work during the day, come home to family time and dinner, then bath time and putting the kids to bed. This is usually wrapped up around 8:15-8:30. Then the wife and I usually have our chance to catch up, maybe watch some TV or a movie or get some housework done. At around 10, she goes to bed, and I go out to the garage from 10 until usually around 1.
It's not a perfect system, and sometimes I'd love far more time at a single go, but it keeps the peace.
Anyway...my advice...you're going to have to give up those long stretches of confinement, but that doesn't mean you can't carve out some time for your hobbies if you work it out ahead of time.
