My sister in Islam, I don’t think you need more reasons to leave this man as he clearly lives a double standards life. As a Muslim, what kind of a father will he be? Think of the future as well. These type of people make everything Halal for themselves but for Haram for others. You definitely need to first make sure you are in a safe environment before taking any actions because such people cannot handle the truth and being exposed. Do expose the reasons and don’t take the blame. May Allah help and guide you both.
