My knee-jerk response is, "blissfully."
I live with my wife, a 19 month old, and two cats. I love them, but I would love, love, love to spend a week entirely by myself - going to bed and waking up on my own schedule.
I took a couple of days to drive to the middle of nowhere in Oregon to see the eclipse by myself. My goal was literally to be as far from other people and as solitary as possible for the whole trip. (Not exactly easy given the expected crowds, but that was my hope.)
I slept in the back of my truck and barely spoke to a soul in 48 hours. It was absolute bliss.
I'd like to figure out to get a little more of that solitude in my life, but it's hard. Anytime I'm out recharging my spiritual batteries, my wife is at home solo-parenting with the kids draining hers more than twice as fast as usual.

I love my daughter. That's the truth of it though. Sometimes it makes me you happy and you want to give and give and give. Sometimes it makes me you unhappy and you want to curse them for their wretched selfish neediness. It doesn't matter though. They'll take and take.
Of course I was the same way with my parents so it's all fair enough. But like you say, sometimes I find myself humming Hungry Heart ("I got a wife and kids in Baltimore Jack, I went out for a ride and I never came back") and just wishing they'd all just leave me along for a week. A day. A couple of minutes.
Was still happy when my girlfriend arrived after a week though. But that one week was indeed 'bliss'.
You almost certainly are. Fifteen years is a long time, longer than my parents were married. You didn't have a break-up; you went through a divorce. A year sounds like the minimum amount of time it would take a person to deal with it. I wish you the best.
