God is Love. If a definition of love goes against God, and His advice and commands, it is not love, for it does not originate from pure selfless love which God alone has. He loves us enough to say NO when what we think we ""love"" isn't good for us.
Love should be to God first and others second. God shows us clearly in scripture, both OT and NT, His will regarding marriage between believers and unbelievers.
2 Corinthians 6:14
Do not be unequally yoked with unbelievers. For what partnership has righteousness with lawlessness? Or what fellowship has light with darkness?
IS MARRIAGE NOT THE ULTIMATE PARTNERSHIP?
1 Corinthians 15:33
Do not be deceived: “Bad company ruins good morals.”
Deuteronomy 7:3-4
You shall not intermarry with them, giving your daughters to their sons or taking their daughters for your sons, for they would turn away your sons from following me, to serve other gods. Then the anger of the Lord would be kindled against you, and he would destroy you quickly.
1 Corinthians 7:39
A wife is bound to her husband as long as he lives. But if her husband dies, she is free to be married to whom she wishes, only in the Lord.
ONLY IN THE LORD, OR AS OTHER VERSIONS CLEARLY PUT IT ONLY FROM AMONGST THE LORDS PEOPLE.
2 Corinthians 6:15
What accord has Christ with Belial? Or what portion does a believer share with an unbeliever?
2 Corinthians 6:14-15
Do not be unequally yoked with unbelievers. For what partnership has righteousness with lawlessness? Or what fellowship has light with darkness? What accord has Christ with Belial? Or what portion does a believer share with an unbeliever?
James 4:4
You adulterous people! Do you not know that friendship with the world is enmity with God? Therefore whoever wishes to be a friend of the world makes himself an enemy of God.
(IS MARRIAGE NOT THE CLOSEST OF FRIENDSHIPS AND CERTAINLY MORE INTIMATE AND CLOSE A RELATIONSHIP THAN ANY OTHER!)
1 Corinthians 9:5
Do we not have the right to take along a believing wife, as do the other apostles and the brothers of the Lord and Cephas?
(IE. NO RIGHT TO TAKE AN UNBELIEVING SPOUSE.)
There is no call for a believer to leave an unbeliever wondering what to do n a situation where one way goes against the will of God and the other does not. Yes of course it is her decision, but the word of God is her and our judge, this is not a matter of judgement but or making clear when one has asked. for advice, what the best biblical advice is, as this is a biblical site and the question was asked by one wanting to serve and obey God.
Hence telling the op what the word of God says rather than our opinions, for God IS her judge and He said it.
