I can completely understand your desire for having your own time and space. It is the same with our marriage as well. We have been together almost 35 years, married for 32 of them. We get on each others nerves rather easily at times. Since I no longer drive, at least for now, she gets the wheel and I have to shut my mouth and be chauffeured. Of course I drive her crazy because my mouth can't stay shut for long while she is driving, there is always some direction to give 😀.
