what is the love body language?

There are many ways that strong feelings are communicated non-verbally. The eyes usually speak the loudest, next to the hands. Holding hands, feeling the electricity, touching the arms, these are signs that are unmistakable. When she looks somewhere else or pulls away from you I suggest to pack your bags and look elsewhere, it will not be a good thing to camp out and wait for her to fall in love with you. You might eventually wear her down with your persistence if that is the way you want to win her.
