If you look at all the answers that these people gave none of them quoted from God's own word the Bible. But let's see what Jehovah God say's about marriage in his own words.
let's first look at Gen 2:22-24 where it says; 22 And Jehovah God proceeded to build the rib that he had taken from the man into a woman and to bring her to the man.
23 Then the man said:
“This is at last bone of my bones
And flesh of my flesh.
This one will be called Woman,
Because from man this one was taken.”
24 That is why a man will leave his father and his mother and he must stick to his wife and they must become one flesh.
The only grounds for divorce in God's view is ADULTRY, as Jesus Christ stated when he was being questioned by the Pharisees about this very question and his answer can be found at Mathew 19:3-6 where he says: 3 And Pharisees came up to him, intent on tempting him and saying: “Is it lawful for a man to divorce his wife on every sort of ground?” 4 In reply he said: “Did YOU not read that he who created them from [the] beginning made them male and female 5 and said, ‘For this reason a man will leave his father and his mother and will stick to his wife, and the two will be one flesh’? 6 So that they are no longer two, but one flesh. Therefore, what God has yoked together let no man put apart.
