Does anyone have any GC enlightenment stories?

Fighting for the soul of a GC. I'm a non-RBN who married one and has been on a nightmarish journey of discovery. I was so innocent and naive before. Now locked in a never-ending tug of war. We have two small kids together, and I know if we were to divorce, his parents would make him fight for custody (he wouldn't on his own because he doesn't like doing childcare) and then his parents would essentially end up with 50% custody of my kids. That would be not-okay because my FIL is a major creep. At least now I can ban them from our home. My husband will sometimes agree with me, but then will get sucked back in by their manipulation. It's like his brain is breaking whenever I point out evidence of their dishonesty and manipulation. He starts to see it and is disturbed, and then he can't handle the truth and reassures himself that they must be the good people they always said they were. Like his brain actually can't handle it.

Anyways, I feel very alone sometimes thinking nobody can understand this situation I'm in. Does anybody have any GC enlightenment tales to give me hope? I think we're making progress, but it's always two steps forward, one step back.
