Does he like me? How should I go on with this situation?

If you (let's call him) Z also like it, then return his advances.
Place your hand on his or support yourself with one hand on his shoulder.
Drop a pen/ruler/pencil "accidentally" and see if he bends down and picks it up for you.
You can also ask him if he would like to go for a walk with you, because you love to talk to him.

Ask him if he'd like to hang out some time, just the two of you (you don't have to call it a date - in fact, don't call it a date). Tell him you enjoy his company and that you'd like to get to know more about him. Like naturelover-VT noted, it doesn't have to be any sort of expensive activity - a walk in a park can work well,
