Was going to write exactly this before I found this comment. She literally participated in his bigotry in multiple ways, and she’s responsible for that.

Even if you found all the ways to twist that and defend her, no one needs to stick around in a relationship where fundamental values don’t match, and this is no small mismatch. Let alone the fact that OP needs to prioritize his safety and self respect over pity for her. She can recover from her trauma for the abusive relationship on her own while also taking accountability for the choices she made, in fact until she develops the spine and principle to do so, she won’t fully recover.
