So - let me see if I have this straight: - you don't have any physical desire for her - you didn't feel connected to her during your engagement but now you really don't want to lose her? - you use porn and masturbation for sexual release
First - I think you have to acknowledge that she's entirely within her rights to leave. You haven't gone to counseling to solve your problem, this has probably been an excruciatingly painful year for her, she deserves better. Acknowledging that to her may actually help her see you in a better light.
Second - do you have any idea WHY you didn't find her attractive? Were you resentful of the fact of it being an arranged marriage? Was she someone you just really wouldn't have chosen on your own? Do you think you had "Madonna/whore" issues, where you felt it wasn't "right" to have sex with a "good" woman like your wife (but okay to masturbate to porn)? Or do you think you have an addiction to porn? Or, possibly, could you be gay and just haven't come to grips with that yet? Clearly, she would be foolish to take you back if you haven't figured this out. Can you find an individual counselor to help you with this? Perhaps if she knows you are actively seeking help with your problem, she will be willing to give you a little more time.
