Hi there, they certainly do like you. In almost every case the popular Guys know how to stir up emotions and raise tension between you two. Eye contact is one of the most intense and important thing to do with any female. If you do like this guy next time he does make eye contact perhaps try looking right back into his and he should come over to talk to you. From much experience I know that you might get overwhelmed but control that, just remember to smile back at him and laugh, after all he should be making you laugh but don't be afraid to contribute to the conversation.
Hope this helps out :-)
