I would like to know if that when a man and woman marry and they did not have God in there life at the time, but later discovered God could that mean that God did not bring them together? If one of the spouses chooses to leave could that be God's will for their life?
I'm very frustrated to see unGodly marriages stay together and then our marriage where we found God together is falling apart. What kind of example does that set for everyone? I don't have it in my heart that God will let this marriage be torn apart.
I am putting in that quote, from your original post, because it is important to deal with. Maybe it wasn't so pretty to say outloud.
Without that, further, all context is removed... and it is difficult to give anything.
There is one reason for divorce, and that is for fornication. A man hates the opposite of what he loves. Men will hate women if they love someone else. It is like Jesus talking about how we can not have two masters... we love the one and hate the other.
So, if you slept with someone else, he has every right to leave you. Otherwise, no, he doesn't have a right to leave you. He is acting out of sin... there is nothing Christian about that.
Relationships are about commitment. That means you are commited to stay together. It is a matter of one's word, at a very deep level. A person who breaks their word in that deep way... is sinning very deeply.
As for you, frankly, I have seen a lot of women have bad men in their lives. If the man absolutely won't try to work things out, you should mourn his loss for a time period, and then move on. If you trust in God, you will surely find someone else much better or in some other way be rewarded for your faith.
As for the godless staying together... some do, but actual statistics show Christians tend to stay together far moreso then unbelievers.
If someone wrongs you, that says nothing of God, because God will ultimately judge them and make that right. But, it says everything about them.
