I had a couple of friends, they were married for 11y, but eventually they did separate. He wanted kids, she didn't.
They met when they where like between 22/25.
He, soon after got divorced to her, married to another woman and had kids....3...
I met her one day and she was desolated....and seemed a bit regretful. Life is made of choices.
Everyone should pursue their dreams but I think is wise to have flexibility and have an open mind.
We never know what challenges life through at us.
