This section of First Corinthians 7 (verses 10-16) addresses two scenario:

1. Whether Christian couples should separate when they have marital problems.
2. Whether a couple, one of whom gets saved after they get married, are obligated to stay together if their life becomes unbearable.

God's desire is that marriages should be harmonious and that couples should enjoy the pleasures of marriage in every respect. If they don't there is a way forward.

May the Lord help you if you are facing these issues.
