+1 based on (n=1) having two kids and being married 15 years. Being with your kids is a flash in the pan compared to decades with a partner. Don’t neglect your kids, but the evidence is strong they’re mostly on rails you don’t control and as long as you care, that’s most of where the effort needs to be. Finding good partners is hard. Keeping them is work. Losing them can be catastrophic (emotionally, logistically, financially) and leave you in a place it can be difficult to come back from. Operate accordingly.
