Hey there people. So I'm in highschool. Few months ago a new guy came to my class and yeah he suddenly started talking with me so so much....like it's been 7 months since we guys are talking almost daily even on text, after talking in school. He teases me, he helps me, he seems a bit possesive also, he's jealous and tells me to stay away from the guys who seem to like me, he had sent me his childhood picture, his family photos and even told almost everything about his childhood and other friends he had from previous school, we two are the only ones in the whole class who play flute together and he always wants to talk with me and wants to do rehearsals with only me, he sometimes randomly texts me out of nowhere...he even had sent me numerous of recordings of his flute, even specially sent a recording on my birthday, his eye contacts are intense and he even notices every small thing even if he pretends not to look in my direction, everybody out there in class thinks that we two are dating.
But the worst part is he's already having a girlfriend from his previous school and he always used to avoid talking about his girlfriend, he had sent me photos of her... even on her bday he was behaving as if he wasn't interested in wishing her...he sent the same flute recording to her that was sent to me on my birthday...
Yesterday in interschool competition we guys met and his GF also came....they both were talking and I was feeling jealous over it.....he just made me feel like a friend to him in front of her....now I don't know why he made it so obvious in the starting that he was romantically intrested...
Even when I came home after yesterday's competition, his messages were there. He had again sent me video of yesterday's competition that I've already seen in front of him, asking that have you seen this ... He again texted me out of nowhere...
Now I can't ask him directly about all this but I'm feeling a bit. What should I do?
