Sounds like your collection of friends generally made poor life decisions in their choice of partners and/or have their own emotional hang-ups related to career–life balance, frustrated ambitions, housework, .. I recommend against projecting this depressing anecdotal evidence on the whole world though. As a counter-anecdote, most of my long-married friends seem to respect and get along pretty well with their spouses.
