When two Christian people get married and their difference overwhelm them because they had collectively turned from God then like the ungodly they think about separation and may stop speaking and respecting each other. It’s hard to see the problem when you are within it but here is one thing of note, when God has joined you together, it is because He wants you together, to be able to work in His glory. I recently heard of the reunion of two lost souls and how it was compared like two blocks of ice melted together to form a more flexible puddle of oneness. During their ice period, the children clung to their mom and disrespected their dad, believing he was the catalyst of the feud. Fortunately God’s mercy is great and His strength is greater. He has given this family peace and from here on they may be stronger spirits.
