This Isn't Cthulhu!

Everyone, I have something I'd like your advice on. I'm the male lead of this novel, but my wife died from the start...

Of course, I refused to give up, so I turned to the heretical path.

After a great deal of effort, I managed to bring her back to life, but... she became an evil god.

Half her soul comes from Abhoth, and her body has also turned into Abhoth's tissue.

What should I do? Is she still herself? Should I accept her?

Please help me think this through, everyone.

One more thing: please reply quickly, because I don't think I can resist her much longer...
