irresponsible father, resentful daughter—both narcissists

I can't say I care at all about this family feud that blew up online, except to use it as an object lesson about marriage and family. Don't get married if you're not mature enough to understand what love and marriage are, and if you do have kids who end up as the collateral damage in your divorce, at least be a responsible parent to them, not some absentee figure who catapults them money on occasion. A good, wholesome, happy marriage leads to a next generation with its head screwed on straight. A broken marriage leads to all sorts of fucked-up results. It's not just your own destiny at stake: others are relying on you, whether you know it or not. As for these two online idiots... have at it, I guess. You'd be prime candidates for Jerry Springer or Maury Povich if those two were still a thing.
