Also speaking personally, I know more divorced couples than married couples, and have seen a married partner (who has a child) cheat on their spouse for going on a decade “because it’s the path of least resistance.” Also saw someone during a divorce light $100k on fire (from combined assets) in lawyer fees just to spite the other person (who had exhausted all options in attempting to repair the relationship before asking for the divorce).

Everyone is winging it, and the only beauty is in finding happiness while causing the least harm to others (imho). Do the best you can with the information you have, maybe it works out, maybe it doesn’t.
