so upset and idk what to do

Like I like this guy A and like our "relationship" is pretty complicated and like I already confessed to him but all he said was okay and before I could ask him how he feels he left and like he always looks at me and he kind of gets jealous when I talk to other guys and he used to get jealous of N a guy who I used to like and like things have been kind of awkward between us ever since I confessed but they were starting to get better this week but then this other kid in my class was saying how I lost my chance and stuff with A and like I got mad and I said I like Nby accident and I think he heard and he got upset and he's been pretty down since he hard and there's this other kid in our gym and he looks like N and like my friends think I like him but I don't and like A thinks that too because he akways looks at him in a jealous way and like I'm confused about these mixed feelings he gives me and sometimes he flirts with other girls and stuff but I heard that boys are like that but before they go to sleep they always think about the girl they love and like now they changed my seat and like I don't sit in front of him anymore and like we won't be able to talk that much which will make thing worse And like I know maybe I should, give up but I know that A will get hurt by the other girls who only like him for his looks and his eyes and like I don't want that because I know how he feels but I feel like he didn't belive me when u confessed to him because he thinks I still kind of like N or maybe he thinks I won't like somebody like him but really I feel like I'm the one who's not good enough for him and that maybe I'm just so stupid
