You have not been in a bad marriage, I take it.
Thankfully not. My wife is certainly a strong willed woman, but she’s also genuinely kind and usually reasonable. We’ve always made things work and I’m thankful for her.
But even in a marriage where things are not going well, I was always raised that the sacrament of marriage is a divine gift and should be treated as such. It’s a bond sealed by God. Breaking that? Better have some pretty major reasons you can explain to Him.
