His position is open
What position he holds and how he holds it is also an important sign that tells what he feels for you. If the man crosses his legs or arms while taking to you, he is not fully open. It may mean that he is trying to protect himself from you and keep some certain distance. If his position is open and he leans towards you, then he certainly likes you.

He becomes talkative when you are around
If your man speaks up when you are near, it means he is trying to impress you and make you notice him. In this case the guy will try to make you smile and laugh by telling funny stories and jokes. In general, men become much more talkative when they are around ladies whom they find attractive.
