You want to know why these issues arise or are never solved? Because they do not know God. Period. Most women become under the influence of Jezebel, most men become under the influence of Baal. If people knew and understood the spiritual reality that they live in and the Man was actually the head of the woman and family it would mean he is responsibility to guide them to God and his superior Will and way of life for us. Even if these issues did arise they are navigable. No one said it would be easy but to give up on someone you supposedly love and care for when they are suffering from the influences of evil or the demonic is the real problem. Believe me I was in a position similar. Never give up you just have to do it spiritually.
Discussion
I notice you are bringing up religion, and previously in this conversation you seem to blame a person for their partner's sinful(?) acts.
I have talked with Christians who said, as I understood it, that it is not a Christian's place to judge faith, and that someone's relationship with God is purely between them and God.
I'm curious whether you have a similar understanding, and whether you believe there is an obligation to judge one's partner's relationship with God before committing to the relationship or marrying then. Can you clarify your position?
“Judge not according to the appearance, but judge righteous judgment.”
In the Bible it tells us “All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:”
Reproof isn’t judgment of faith and it doesn’t talk of judging one’s faith. What’s wrong is judgment of others sins when you are also sinful. No one could ever actually judge someone faith anyway we are not mind readers we do not see all.
The point is you still need to have discernment. Are you and your partner equally yoked? In corinthians it speaks a lot on this topic of relationships, marriage, sex. For example “If any brother hath a wife that believeth not, and she be pleased to dwell with him, let him not put her away. And the woman which hath an husband that believeth not, and if he be pleased to dwell with her, let her not leave him. For the unbelieving husband is sanctified by the wife, and the unbelieving wife is sanctified by the husband: else were your children unclean; but now are they holy.”
if at least one in the relationship is believing the other is sanctified by them. This is why the “two become one” is very big. In my experience being with someone who is unbelieving is actually very difficult.
Their principles and values usually differ. I like to also point out that the head of every man is Christ; and the head of the woman is the man; and the head of Christ is God.
Man is the image and glory of God and woman is the glory of Man.
So remember whatever problems you get into, you got there under your leadership. If you want your partner to be well kept to be lovely and honorable you need to be the example.
Ephesians 5 explains very well how a man and woman should treat each other in a relationship.
