How can you tell if a guy's intentions?

This is a large question(s)

1) how do you know if he's being nice vs he likes you

2) he wants to JUST sleep with you vs dating/actual feelings

3) are there any ways to tell how a guy views you by actions? Examples?

4) are these signs of interest:

guy breathing heavily around you?

Looking at your lips?

Touching you (hips, waist, hand, arm), BUT NO IN A CREEPER OR SEXUAL WAY

Other signs?

Sorry for all the questions . I will answer yours
