I can appreciate the difficulty and struggle with your situation. It would be impossible be for me to know her intention, but what seems very clear is that you do not trust her. You don’t feel she loves you and you feel you were tricked into marriage.
It is important to honor these truths in yourself.
Because this was an arranged marriage and there are familial and cultural elements around this bond, I would encourage the consultation of a spiritual counselor from your religious community rather then a psychological counselor. What is necessary here is for the counselor to be told the whole truth about the background and current situation. While you agreed not to tell the parents I believe it would be important to seek guidance from your religious community with a person who has access to the whole truth. This will give you the best possible opportunity for a resolution.
