I wouldn't sweat it too much. Sounds to me like you've found peace in reading through tough times. Maybe that's your new gaming. I personally bounce between things. Read for periods of time, then game, then watch movies/TV. Right now my infatuation is with the new Final Fantasy as I've been wanting a narrative driven game, and it's satiating that craving so far. After I beat this game, I'm going into patient gamer mode for a while, and picking up my dormant guitar that's sat for 10 years. I love music as well, so I want to up my game there and start to learn from scratch. If games fall by the wayside while I explore guitar then it's okay, I will find my way back to them when something strikes my interest. Until then we must follow our urges and let them go where they may.
I can't speak to being a step parent, I'm single and don't desire a relationship right now so I have lots of free time. I just realized over the years that I also don't want to look back and have all my time spent on one hobby that doesn't leave much to show for.
