If parents don't accept - and the guy is waiting on parents approval - then you must run and hide ASAP. Never ever show your face again to them.
If the guy does not care for parents approval, then you better believe he wants to make this work.
i don't see why its so wrong if the guy is trying to convince his parents for you and trying to make things work and do things the right way ... i'm sure you'd feel alot different if the tables were turned and the grl had to convince her parents ... the guy caring for his parents approval just shows that he wants to do everything the right way and also is a family person who respects his family enough to convince them rather than just do his own thing
