Yo Bull... I ain't no relationship expert however before you throw your nice sweater in the river I would suggest you to confirm if her feels for you are for real cause you might regret it when winter comes in Chicago. Next time when you chat again, tell her that you are never gonna get Perm. Residency and that you are planning to come back to Nepal to be with her for good. And see how she reacts to that. If she continues to be nice to you and still wants to be with you then you are right on the money. It is about your life..nothing wrong with making sure if she is a right person for you. Good luck.
