You are correct. People seem weak nowadays and give up on the first hurdle

My grandparents still together. That's a different generation.

Still married since August 1980

I only know one couple who made it more than 10 years without either divorcing or just constantly batching about their supposes. Usually lay behind each other's back. My neighbors have made it 22 years and know how to keep it up in a very positive and fun way.

You have to have the right relationship to fight for….and I certainly hadn’t found it at your age. I’ve been married for a while to someone I love deeply, and although the marriage is far from perfect (no sex in over 10 years), we haven’t given up on our relationship.
A lot of my friends have been married as long as or longer than I have, so there are a number of people who still do that these days. Maybe you will be one of them when you find the right relationship.

Sometimes I think it's better to get a divorce than to live a failed marriage

I think when one of the parties no longer feels love for the other person it's all over no matter what you try to do to fix it.

I find couples who immediately get divorced amazing.

Me too.

my parents I guess

We don't because modern western society encourages people to live for now, sleeping around, drinking, rather than creating a strong family, keeps the elites in power
