No one knows what they want for the rest of their lives when they're 34 anymore than 24. Same for 44, 54, etc. we're all figuring this shit out together.
But I'll pose another hot take:
Marriage is stupid in general. Pledging to commit your life to another person is stupid, and you don't need a church or government to recognize your commitment. If you end up hating each other somewhere down the road (which is likely) there's no sense in continuing to torture each other. It's not good for anyone. Get divorced? Well then what was the point of getting married in the first place? It's supposed to be a lifelong commitment.
I'm not a "stay together for the kids" kind. But if you do have kids, I think you need to try and work shit out, get professional help, etc. Before giving up and destroying everyone's life.
