How did you know it was the right time to quit?

Hey ladies, I need some outside perspectives. I have been miserable at my job for a few months now. I want to stay home with my little one, but we weren’t able to afford it...until now. We got rid of a lot of debt that we didn’t think we’d ever get rid of and my fiancé makes more than enough to support us. We get married in a few months and he told me that after the wedding, I could quit and stay home. We have about 6 months worth of bills saved up, I have been waiting for this day for what seems like forever but now that it’s so close...I’m not sure. If I don’t bring any money in, then it will take us longer to do things like update our house. I don’t know why I’m so hesitant now all of a sudden. Is this normal? How did you know it was a good time to stop working and be a SAHM?
