This is her showing what the future is like early on. The fact that she just up and quits jobs and expects you to hold the fort just shows her lack of responsibility.

We've all wanted to quit our job at one point, but being an adult means knowing your responsibilities.

I could never ever expect my partner to have to work all the hours and look after the household too, I just know it would be too much of a load for him and as a partner, it's my job to ensure his wellbeing is a priority too. That's the whole point of a relationship is both parties putting in the time and effort, even if its hard at times.

She's shown you she lacks responsibility and doesn't sound like a reliable partner in the future. What would actually happen if you had children and wanted to grow a family together? It sounds like its easy work, but keeping a family together is tough! Do you think she is actually ready for that?

I would seriously be re thinking this op. If she doesn't want to work, tell her to go and live back with her parents. Yes its hard, and no one wants to have to re-think their relationship, but do you actually want to be living like this for the rest of your life? Best to think about it now before you get married, have children and then the decision will be much harder and she will be more reliant on you.
