The majority people in the west generally live together and marry afterwards.
In the UK more children were born out of marriage then in marriage when I checked the figures a while back.
In the US, there is a strong anti-American woman feeling among the men. They feel that they will marry, work hard to develop a business, then their wife will divorce them and take half of what the've earned. To that add the decline of the American women; overweight, unfeminine and lacking in housewife skills. Hordes of US men are going abroad to Asia, Eastern Europe or south america to find a bride that is still feminine.
They will go abroad and describe the women as 'sweet and feminine' ie the way women are natuarally, not wanting to be 'as good as a man'.
Google 'mgtow'. 'Men Going Their Own Way'. A style for men of basically doing without women, and spending all their hard earned money on themselves.
