feeling bad that i came out

i came out to my mom that i’m bi. i’ve just accepted myself after years of battling myself whether knowing or not that i am since i was 13 because there had been moments in my life that i felt infatuated with a woman and i thought maybe i was exaggerating or being silly with women crushes lol. i’m also in a relationship with my bf and he knows about my sexuality which he accepts me and still loves me. i love him very much and i’m very lucky to have him. anyways after 8 years, i’ve accepted myself being bi and came out to friends, my bf, and my siblings. when i came out to my mom, she said “you have a boyfriend who’ve you been with for almost 8 years.” “it’s very normal for a woman to be easily attracted to another woman. it’s common.” “i am not against it, i just think you’re confused.” i’ve expressed to her how i’ve dealt with this myself even before my bf came in the picture and i told her how my bf even knows about it and that he accepts me and still loves me but she still tells me that i’m confused and got offended when i asked her, “why can’t you accept it?” it was intense and i felt bad for even telling her... i’m in my head thinking what if she’s right? i mean i’ve never kissed a girl (well sort of. she kissed me and it wasn’t consensual and from a girl i wasn’t attracted to) or been with a girl :( besides all the girls from my town weren’t my type and MEAN aha but i’ve had felt butterflies, excitement whenever i saw a woman who i just wanted to kiss, cuddle, and just devour sometimes... idk rn i feel like shit and stupid :( i know now not to tell my mom shit anymore.
