'Flows before ho's....' Simple, I like it!
I already gave up one flying career for a wife candidate. It was the biggest mistake of my life. I think about it, and regret it, at least once, sometimes more often, every day of my life. This mistake of mine leads me to where I'm at: I'm a mid thirties, rookie FO at a regional, where my peers from the time of the 'girl/career' decsion are 0-4s flying F-16s, or, 767 FOs at a Legacy.
Suppose you jettison the flying career to get a normal 9-5. What's to say she wont later dictate that she doesn't like your 'new' career and make you start all over? Maybe she won't like your car. Your routine. Your hair. What's next?
I know that this is a difficult time for you. Please, for your own sake, don't do it. Have a straight forward, open conversation, not argument, with your significant other. This issue could simply be an issue of communication. However, if not, it is FAR better now that you settle your tab for 'pain' at the bar of life, than to wait until the end of your working life to pay a bill of regret. Regret later is FAR worse than pain today.
I don't know you, or all of your story, but I'd guess that flying is a big part of your life. Simple question: do you spend as much time on wwwtheknot.com as you do on FI?
