I know a convert lady who left Islam for a couple of years because of a bad marriage, the husband was being heavily influenced by his cousin who was one of the biggest Islamist misogynist I've ever come across (!). But then about a year before I left Islam for the last time, I heard she had remarried a convert and come back to Islam. I think her reasons were emotionally as well, she couldn't keep up with the "obedient Muslimah" role she was assigned, especially in her context where the wife (the "role model") of her husband's cousin was... well, let's just say it's depressing...
I have had a lot of thoughts about this. I think in Islamic culture, your Mahram makes all the difference in the world if you are female. If you have the support of your father and brothers, your husband is probably going to be supportive, too, if he wants to keep you. If you do not have the support of family, then all your life depends on your husband. If your husband does not want you to go out, to talk to this person or that person, and give such reasons as they have a ¨flawed Iman" or whatever, what can you do? In conservative Islam, it is his right to dictate these things. To argue against him is to argue against Islam.
I once took a girl who had fled a very bad husband to the local Imam to get a divorce decree. Even in the face of horrid abuse, inhuman abuse, that Imam would not do a thing, even though it was in his power. I was so astounded, I was sure we had made some sort of mistake in communication. But no. The Imam was like that. Probably they are all like that. I have never heard of one who was helpful to a married woman.
When your Mahram is bad is when the issues with being female and Muslim come to the fore. It is a hell, and following Islam becomes an oppressive choice.
I understand this lady completely.
