I would say think very carefully before deciding if you want to marry her. This advice applies to everyone really, but especially to you as this incident is a signal that there might be some incompatibility in your values, which is a warning sign. I'd say try and take this to the ultimate conclusion of resolving the topic amicably, without either side just giving in. Don't shut it down or put it off. A fight, or even a break up is better than carrying on as if it doesn't matter. This would be a good test of how things will go once you are married. Also read some books on choosing a partner / comparability. I would say that this should be the highest priority thing for you so ditch any side projects, say NO to overtime and sort this one out. Good luck, and feel free to take this unsolicited advice with a pinch of salt :-)
