I need help...

Okay, so me and this boy I know were enemies ever since the 1st grade. We hated eachother sooo much!! But then in the middle 5th grade he started being really nice and polite to me all of a subben. He started Актёрское искусство sweet and caring and he acually talked to me еще often then he used to. When I left my school I was talking to my friend on the phone (who still goes to the same scholl as him) and she сказал(-а) that she heard him say to his friend in the hall way "Man, I miss Brianna (my name)". I kind of like him but I dont know if that means that he likes me back или he just plain misses his old enemy..another boy was like that too, he was also my enemy but then started Актёрское искусство super sweet and he was putting his arm around me a lot. I have no idea what both of the boys were trying to say. I dont know if they were trying to say "Hey, I like you" или "Hey, I want to be your friend".
Please help me cause I'm soo confused!!
