Help please

So my bf orders originally was VA now that he made E6 he went to Germany his orders says 2 years but I FaceTime him through Facebook on yesterday and now he thinks he will be there for 3 years we got into an argument over how long he will be there. Do y’all think I’m wrong for telling him that’s too long to be separated? I told him we need to get married so I can be there with him. Any advice please
