This is something my wife are still trying to figure out; you can trivially love two people, or more, but how do you get enough time in the day to cultivate the relationships to their fullest?
It's like trying to grow a dozen apple trees in an average sized back yard. There will only be room for 4 within a decade. My wife has tried dating and it looks like she can make a couple dates a month, and that of course is wholly in satisfying for R2. We barely have time for overnights ourselves, what with two kids, so it's kind of unfortunately ironic when he asked if that was a possibility.
It's a struggle to get to kids to bed by 9pm and then spending a little time together before we fall asleep and then have to be up by 6am. Maybe that's worth a thread itself.
