Crossing your arms could be one of many things in body language….one obvious one is that they were cold. Another reason for a person to cross their arms during a conversation is as a signal to the other person that we do not pose a threat to them. When some people cross their arms, it is to protect themselves or as a self-nurturing-thing.
When I do it, it’s to appear more relaxed then I really am when I am being confronted with something. There’s really many different reasons for crossing your arms. A lot of times when people are truly relaxed they will cross their arms and think about or concentrate on what you are talking about. Autistic folks may look as if they are staring off into space thinking about something else when in reality, they are really thinking about the conversation. Try to remember, some people are not good at talking about their feelings….I am one of them.
It's possible with time, this person will open up more. It's also possible that they may never be as open with their feelings.
The question you should ask yourself is... do you see this to be a problem for you in this relationship?
