Actually, you hu*****and can file his I-485 only. Once get approved, it's very easy and quick for you to get GC as a family member.
But chances for NIW is about 50/50, whereas for RN GC is 100% if you pass visa screen. So, study and pratice hard, try to repeat every sentence when you watch TV with caption on, try IETLS, you are only one step away to guaranteed GC. Some adult schools also have very good free oral English classes, try to find one in your area.
