I have a Situation, can someone help?

well.. he probably has started really liking you and just doesn't know how to act around you anymore so he's being weird. if you like him... i wouldn't consider it "stalking." trying to hang around you more would be considered a good thing in that case. why don't you try and talk with him more and see if he gives you extra compliments or seems more shy than before... then he probably is really into you. good luck!
