She need to realize she will die in that house if not for issac

She is trying to protect him from that toxic house.
They have been in a little "bubble" that's not going to exist forever. They are going to be discovered. And even if they aren't, her husband's plans for the vampire are horrible.
They could run away together, but they would be pursued. His existence would be revealed to the public and he would be accused of the killings. And that's how a witch hunt begins...
I think she wants to do things the right way. Divorce the real monster, get what she deserves (funds to live with the vampire) and then she can live happily forever.
The problem is her husband would never give up the title he got through marriage.
He already has a plan to send her to a mental institution and when he finds the drugs in her room, things are going to get ugly.
Such moments yup Just the happy two of em
