Alexandria
I'm a junior in high school and I just transferred in last year and theres this guy in my math class and throughout the year we became friends and around April I found out that my dad knew him when he was younger and used to coach him .... me n the guy are just friends but in the beginning of this year he started acting different and being more friendly toward me and I just found out last month he asked one of his teammates about who I am as a person and what kind of girl I am..... me and my dad go to all of his games and I even made him a senior poster for senior day .... I think I'm starting to have feelings for him and I think he doesn't having feelings for me anymore .... I only say that because he has my number and doesn't text me and when he sees me he calls me bro.... please give me advice how do you think he feels about me ??? I'm I too late 😩
