Before I say anything I want to tell you that his behavior is not your fault. Additionally, the way he may feel or act out in reaction to what you have done to better yourself is also not your fault. I am not a licensed therapist but I have experienced emotional abuse since childhood; despite that, I am still going to link you to some articles that may explain emotional abuse better than I can.

I agree with everyone else. Talk to someone, most appropriately your therapist. I'm not going to tell you to just leave because I know it's not that simple; although objectively that does seem like the best course, it's often easier to say than do. However, looking around for a place just in case may not hurt.

I wish you the best.
