I am just wondering why it is ok for women to leave a Christian husband, but not an unbeliever.
I take it you believe Paul's writings are not actually important to Christians.
[1 Corinthians 7:12-16 NKJV] 12
But to the rest I, not the Lord, say: If any brother has a wife who does not believe, and she is willing to live with him, let him not divorce her. 13 And a woman who has a husband who does not believe, if he is willing to live with her, let her not divorce him.
14
For the unbelieving husband is sanctified by the wife, and the unbelieving wife is sanctified by the husband; otherwise your children would be unclean, but now they are holy. 15 But if the unbeliever departs, let him depart; a brother or a sister is not under bondage in such [cases]. But God has called us to peace.
16 For how do you know, O wife, whether you will save [your] husband? Or how do you know, O husband, whether you will save [your] wife?
Your problem is that you are listening to someone(a flawed human) from biblegateway. Also, back then, husbands could have several wives. Men could support themselves and their wives; usually wifes could not support themselves in that culture; and, the divorced wives would go homeless and destitute if their husbands divorced them. Also, in that culture, a divorced woman would never be able to find another husband; unlike the husbands who usually had several wives. Women could only have one husband. The only sexist double standard here was their culture, not in what Paul wrote here.
