Older guy always stays to talk to us. Why did he say this? Does he think I've fallen? Or has he got feelings?

i think he is very attracted to you. it sounds to me like he wants to keep things going with you. you both seem to have some attraction there for one another. i would suggest try pursuing things with him and seeing where it goes. he sounds like a good guy who isnt going to play games with you and waste your time. good luck
