Does he like me? or just being friendly?

i've met this guy a few times and recently we've been joking and stuff like he said i work on a farm and raise pigs because i have a "farmer" accent, anyway we look at each other a lot and smile and the other day he just kept nodding at me when he was standing opposite me i wasn't sure why but the problem is i don't see him often last time i saw him was 2 months ago and he works in a casino which means he meets new people everyday and stuff so my friends were like he probs does that with everyone and when i was talking to him this guy called him a charmer, and im not sure if he's just being friendly to me or likes me? and im not really sure what to do he jokes and was copying me when i coughed and spoke to someone and was like im sure they raise pigs and looked at me, but i really start to miss him so badly it makes me cry and upset so im not sure what to do D:
