I work with a lot of young people and see the same. I think another bar to marriage is social — if they can’t afford a wedding that looks like a Hollywood production on social media they postpone it indefinitely.
Courthouse weddings or a Saturday afternoon with cake, mints, punch and peanuts in the church fellowship hall are long gone.
The sad thing is that the wedding celebration sometimes lasts longer than the marriage. Marriage is just an excuse to have a big party, to some people.
I saw that there was a show where couples compete to have the “best wedding”. Gag. My parents got married with the cake reception in the basement of the church and went on to raise 12 kids and show us all the meaning of commitment, forgiveness, and love. I pity the kids today - including some in my extended family - who have bought into this world’s lies. When you cohabitate you practice the skill of sleeping with somebody you’re not married to. There is a reason that cohabitation before marriage increases the likelihood of divorce.
