Why wont this girl belive me or is she shy or something?

long story short i like this girl it was obvious she liked me aswell but we were always messing with each others heads. so today i say who you love she says no saying but asks me who i do. so for once i quit the mind games and told her "love you baby"lol. for a while kept say do you?, really you love me?, i said yh how many times do i have to say yes she said lots then said she was joking. then again said really do you abit random but ok, then asked me again who do you love, i said you you yuo you. then she started to say naaa you dont, how come do you. i said i really do trust me and she said why my i said theres something about you that makes my heart sing (lol that aint a pic up line its the first thing that came to my head). then she said naa i bet your lying you dont you just trying to make me happy so i said ill say it infront of the whole school if you want so she said please dont and it kinda ended there so what does that mean??????? did shes belive me
