I’ve been with my wife for 13 years now, and married for 8. It’s been an awesome experience for us, but I know neither of us considered marrying any of our previous partners. If we hadn’t found each other, I’m not sure I’d be married at this point. Marriage in and of itself should probably not be a goal. It’s contingent on finding someone who you really want to be married to.
Having kids is the same way. It shouldn’t be the default, it should be the thing you do when you truly feel it would add value and meaning to your life, and be worth the tradeoffs you’re making. I hope that society moves more in the direction that both marriage and having children is something that you can choose to do, or not, and there’s not an implicit judgement on you for failing to meet norms that honestly don’t work out for the majority of people.
