This is a complex issue covered in many books. The young man's frustration is understandable but he needs at some point to 'accept' it. (a fella this intense, is a bit of a 'control' person, or maybe a girl just recently broke off with him). Even previous generations or cultures, men, on average were around 30 yrs of age to marry.
People, including the females, don't want to settle down in late teens or early 20s, as in previous generations. Some females have seen their older female family do the commitment, some too submissive and found themselves burdened & struggling.. Thus the social pendlelum swings.
It is understandable why young women want more & better. However, then, many go and out, round and round, in revolving door relationships. Some still find they are accepting for a while less than desirable relationships over and over. Not getting much of anywhere. The goals and idealism confusing to both genders.
I am a grandma now, 5 grown children, 2 daughters (each married, happily), 3 sons (single), so I hear both sides. The sons ( 32, 29, 27). The 32 yr old in a promising relationship, the 29 yr, frustrated presently (but very busy building career), the 27 yr. totally happy being in no relationship, busy traveling and working along the way whereever he goes.
