Re: How to tell you are not being used for greencard?
Well, anyone you will be marrying from Pakistan in an arranged marriage will of course be marrying you for your Green card. There should be no surprise there. But the thing that you need to make is he is NOT solely marrying you for the green card and that he genuinely likes you. Problem is figuring out how much weight does the green card had in making his decision to say 'yes' to the marriage. That I don't know if you can ever found out except of course after marriage. Best you can do is make sure his family is educated, not greedy, value family and relationships etc.
