Seems your parents doesn't know the foundation of a relationship. It is LOVE. It is not because you need to work out your PR and be secure with financial status, etc. They are to the point that they want to protect you but it's your life. You won't be able to call it your life as to everything they are the one deciding for you.

Sorry, I don't have any concrete advice about this because I don't want you to oppose them but I think you need to talk to them. You're a grown up woman, not a little kid anymore.
