Although a totally different case, one of my friends went through something like this a few years ago. They agreed to not to have kids, she changed her mind two years into the marriage and put on the full court press. She threatened divorce, he drove her to the court house at that exact moment and she filled out the forms, relationship over. Two years later, she still doesn’t have kids…hmmmmm.
I am not saying run to the courthouse is the route to take as I don’t know all the facts involved. Sounds like there is more to unpack than meets the eye in this relationship.
Why now? Health kick? Dig deeper, you may or may not like her answer, but you owe it to yourself to find out the real reason. ASSumptions become facts when you don’t have open dialogue with each other.
We all have different opinions on what matters to each of us. Do what makes you happy despite who agrees or disagrees. YOLO!
