Doesn't marriage mean saying goodbye to financial freedom?

‌Based on the standards of an average office worker
If I live alone
And save my salary to invest in a mix of QLD and VOO
I could build meaningful assets by around age 45
And I could probably retire around then. If I'm alone
Of course, a combination of a man from a large corporation + a woman from a large corporation would be a different story
But I am talking about the standards of an average person
Furthermore, if there isn't much family wealth either
It seems like I will eventually have to choose one or the other.
