She likes that I don't waste money on useless shit like everyone else but rather save such that I can finance studies at Stanford or some other good school for our future kids, if they desire to do so.

Having kids will mean I can't retire in 5 years but maybe in 15 years. In any case I have a heads up compared to everyone else. Having tons of cash on hand and little expenses gives you sort of super-freedoms other people don't have.

I am frugal and like many people here also attend to my side project on nights and weekends, committed relationships are off the table with this lifestyle (sure, there might be rare exceptions).
