I am puzzled please help me?

I am 13 and i was at a dance and told my friend that i liked a guy. She ran up to him and asked him out right then and there! He said yes but I wanted to get to klnow him better. Anyways....I really liked him but it was too wierd cuz we didnt rly know eachother enough. Hes my age btw. Well cuz it was so weird i broke up with himm but really like him. he is now (4days l8r) GOING OUT WITH ANOTHER GRL ( she told my friend she only sed yes cuz he was being nice to her thsat day) Well...ever since i broke up with him he stares at me...but in a good way. Yesterday the hall was empty and he ran pst me and looked back with a smile. I'm usually rly outgoing but with him i am really shy. Please dont say he is a player cuz he is not and dont say he is just playin a game with me cuz he's not. I always end up werevr he duz. ITs SO WEIRD Everywher i go even during cles he ends up there. I really like him alot! Is that a sign of him ending up whereever i go for about 2weeks and what should i do?
