bisexual ?

So I have a bf , butttt I have a very deep secret I have never told ANYBODY , and will never be able to no matter how close I am with somebody . But when I was like 11 I had a girl bestfriend n we would do grown things like kiss , all that nasty shit that i will not go into detail about bc I’m not proud of it bc I was young but that’s not the point so pls don’t bash me for it . But I mention this bc I feel like this may take part in why I feel like this . Lately I’ve been feeling “attracted” to girls . But I can’t see myself with one ( I think bc I’m scared of judgement from family n strangers ). I got this one app looking for a girl bestfriend bc I lost all my friends ab 2 yrs ago 🙁 . So I’m swiping on all these girls hoping to find one in my area , I love my bf but sometimes I need a break and an actual GIRL friend to go to . Anyways , I’m just feeling like I may be bi but I might just be denying it bc I’m scared to admit it. For awhile I’ve brushed it off saying to myself “oh I just think girls are pretty nothing more” but idk . I just dont feel like myself and I feel like I’m trying to act like I’m somebody I’m not. I’m NOT saying I wanna break up w my bf bc I wanna spend the rest of my life with him but I feel like this is something I’ve been hiding from myself . I don’t know if this is some type of phase or something but I wish I could be true to myself. It’s just so complicated idk who I am or if I truly like ONLY boys . Any advice ? Please be kind I just wanna see what you guys think or have to say about this .
