I don't see this as adultery, especially since you have just had conversations, and his wife has presumably abandoned them.
The Bible has allowances for divorce, so there is no evidence that God will shun you for getting involved with a man who has an estranged wife. But be smart. Ask yourself why a man living in a state with a population of 19 million people hasn't found a woman there who trusts and understands him.
The Bible mentions the ability of a man to send off his wife with a written announcement that it's over. Basically that's what you are looking at. In the US, the signed paperwork needs to be filed with the town of residence.
This man is an american and I'm in a very far country from his, so I don't know the laws out there. And as a christian, I also want to know what I can do and cannot do. As for him, he says he fears God but I'm not sure he's born again.
A practicing Christian usually says they
love God.
People who claim they are God-fearing can be Muslims, Hindi, Baha'ii...any religion using a generic term for their higher power. In American-influenced countries, anyway. If you believe it is important for you to marry a Christian, try to pray with him and see what his approach is.
I know that you are asking a question on divorce and remarriage, but reallyreally listen to what others are saying. No one can get a feel for what life will be like with someone until they spend some time with them. Do they watch TV 24 hour hours a day, do they show up late for work, do they work at all, do they get so absorbed online that they have no social life or exercise, does he mistreat his child.
He can say whatever he wants online to get what he wants, but if you are going to sign on to a partnership,
know what you're getting into.
To me, it sounds like he wants a woman who will watch his baby and cook for him ... and he knows American women don't readily agree to that. Especially in New York, lol. They would consider a man like that lazy and insulting.
Women in certain countries sometimes want to marry their way out, so he might look for one that might see him as having something they need -- the citizenship. That might not be on your mind.
Be very, very careful.
