Did your relationship change after you got married?

I’m heard many comments over the years about getting married changing everything.

For example

* the honeymoon stage ends after your get married

* ones you get married, they stop trying

* after marriage everything goes down hill

* they let themselves go after marriage

Me and my fiancé are finally getting married after 11 years together. We weren’t in a rush and got together young in high school. We’ve had normal ups and down that every couple goes through. But nothing extreme never cheated, never broke up, no abuse. I really don’t think marriage will really change anything for us we been together so long and know each other well. So my question is did marriage change your relationship? And how did it change?
