i call bullshit on this fantasy story/delusion.
you are much too traditional for a longtime gf, the fam wants a wedding
for their dear boy.
you are fighting the inevitable, a textbook suburban lifestyle:
the house, the wife, the 2 kids...you already have the house, are smitten with this chic, and you bareback it (eventually leading to kids). embrace it bro, i'm happy for you
