Dear Merry, I appreciate you are reaching out to communicate. I am held back because I do not know all the unwritten and written rules of your culture.
From US, your situation sounds very distressing. In this culture woman would take steps to assert her rights as a human being, but I do not know the nature of marriage relationship and your rights as a Pakistani woman.
Your husband is not beating you physically but is keeping you in limbo. I don't know why. Maybe a woman's group could help you define your options if you feel you are withering in this oppressive situation. I really don't want to tell you what to do because I do not know the consequences, but it feels like things are getting very hurtful inside for you. I am concerned for your emotional well being.
