He reads to me as a fairly typical 25-39yo male with a big-ego athletic pursuit who isn’t dreaming of family and corporate job. He liked having his cake and eating it. He never proposed to his 35yo live-in girlfriend who was administratively organizing his life. He picked up M on his BMW motorcycle and tried to convince the girlfriend after he was dropping off flowers (ever try to motorcycle with a bouquet?

).
Maybe this is because I have a circle of friends and history a lot like M’s (different sport but similar profile of academically successful Ivy grads and self-perceived rock stars) - but I know DOZENS of men who lived their 20s like this, multiple women, usually two or three at a time, always a main sacrificing syncophant at the house without a ring and the captivating two or three rotating side pieces. I’m not making excuses for this guy. I am saying he’s not rare. He was just out for his own cake and he never stopped eating it.
