Is it OK to love someone after marriage?

So, it wont be wrong to say that people do fall out love, regardless of how passionate or all-consuming their love once was. Even though most of us have experienced falling in and out of love at some point in our life, but we rarely acknowledge it.

What does the Bible say about falling in love while married?

Ephesians 5:25: For husbands, this means love your wives, just as Christ loved the church. He gave up his life for her. 9. Genesis 2:24: Therefore a man shall leave his father and his mother and hold fast to his wife, and they shall become one flesh.
