Hmmm Marriage they say is an institution where you never graduate. You keep learning for the rest of your life. And you can apply other people's case into your own situations. Because you will have your own unique experience in it, different from other people's experience.

Since marriage is FOR BETTER AND FOR WORSE.
Divorce is never an option.
Even God said "I hate divorce" Malachi 2:16

When you are going through the WORSE which is part of the agreement and vow you took.

You can sepperate for awhile, but not divorce. And that's if life is been threatened.
And after sometime with God you can come back together.

Most people leave God, that instituted marriage out of their marriage. That's the reason for the challenges that always lead to divorce.
When God is in your marriage and you going through, turbulent times. God will definitely see you through.
