Hello lorcar, as an adult beginner also with almost same circumstances with you(except for the baby, forever alone

). With that type of lifestyle it's hard to comply with the time demands of the piano without compromising other areas of life. As my new teacher said "to fully appreciate or learn the art, you must sacrifice an aspect of your life". I'm applying this quote to myself right now, before I became obsessed with the piano this is how I spend my time:
1. Work for 9-10 hours.
2. Rest for 8-10 hours.
3. Spend free time playing games and cartoons.
4. Hanging out with friends on days off, or playing games til' my eyes start to explode.
Then by last year, maybe at the month of august my "calling" had begun. I'm starting to have dreams regarding the piece(s) played by my grandfather, and the piece(s) that I played when I was young. it felt like I'm having a nightmare because I didn't have a piano at the time.
But then I got my first digital piano this january, then my daily routine started to look like this.
1. Piano for as long as time/body/mind allows.
2. Working fast and striving to go home early
3. Sleeping for 4-6 hours.
I sacrificed social life, gaming, and if I don't watch out, maybe I'll end up sacrificing my job as well(hope that does not happen.)
Music has always been an important part of our family, sometimes my uncle and mother would just wander around me when I'm playing my finished pieces. They hate it when I practice with headphones on. My greatest inspiration of music is my mother, who works her as* off while raising me and still got the time to learn the heroic polonaise op 53. Of chopin, she still can sight read the score up til now, but the interpretation.

I didn't know if what I shared is relevant to what the OP was asking.
Anyways, goodluck mate, if you truly love music that much, you'll almost surely find a way to practice little by little without compromising too much of your time. Use the goal oriented practice sessions.
