Annoying boys

Eve

So there is this guy and we go to school together and we have a few classes together and I started developing feelings for him and I liked him for three years before I decide if I don't say something he might never know how I feel so I told him I liked him and he told me he felt the same way but wanted to focus on school because we had exams coming up and we'd talk about it after them but then exams finished and it's been two weeks and I haven't heard from him and this new account on instagram started texting me and asking me about him and I have no idea who it could be but I feel like it might be him and his brother because his brother started texting me like five minutes later and I never talk to his brother and now I have no idea what to do 😬 Any suggestions?
