This is very interesting
it's Stockholmer syndrome the way she fell in love with him since they have similar backgrounds of abuse they could understand each others pains which is why she fell for him and I thought that was ok also the plot twist where it was like he did this multiple times and he's kinda a big fat liar was good ok take that bad I think that after knowing that he was a liar and serial killer I think that is enough to make you lose love in someone but it's cute actually
The marriage was also pretty good too bc like I can understand why she did this. I like the guy but... bc he doesn't know anything that happened to her he is saying these rlly triggering things to her which is why it's just pushing her away from him
Overall I quite like the story and looking forward to the ending I know for sure that it ends in death in jail or smt bc this can never be happy
