@Farooque100,
I agree with Jespah. She is not worth your time.
Not every relationship is meant to be. This woman is an obsession, there is no reason for you to act on it.
Accept the feelings you have for her as what they are, an unrealistic obsession. Don't feel too bad, many of us have had these feelings. But they don't ever turn into a healthy relationship.
Your goal should be finding someone with whom you can have a healthy relationship. That means getting over these feelings for this woman.
