Any ideas? please help D:?

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 and im not sure if he's just being friendly to me or likes me? when he was talking to me some guy turned to us and said your a bit of a charmer arent you to him, 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 and recently when he's locked eyes with me he's slowly been nodding at me and i wasn't sure why i was talking of anything he was standing opposite me and i was getting confused any ideas? i dont see him very often like once in two months but normally he smiles at me and looks at me, and last time he was talking general to me about xmas and stuff but this time he started off slowly nodding when he looked at me and i was looking at him and i havent got a clue why it confused me any ideas? please D:
