> Before, I think my manager saw me as ready. Now I think she sees me as a liability.

Did you talk to her about this? Did you ask her what can be done? This entire situation is painted that you're the one to blame. There are 2 sides to every story, your company can set realistic expectations. It sounds like your work is solid and that people respect you, but that your management has unrealistic expectations about your velocity. A compromise can be reached.

> PS: I'm getting married next month. Will I have to choose between my marriage and permanent 12 hour days?

Yes, and your marriage is more important. Unless your job is incredibly fulfilling and meaningful, it's not worth working 12 hours a day.
