Am I bisexual or it’s just a phase? [16 F]

So I know that I am physically attracted to men but there’s some time back then that I used to watch just girls on girls stuff(and imagine my girl friends) and I thought I was bisexual at the time but it lowkey faded away overtime since that happened when I was just a tween. Then, around a year or two later I went to a concert alone and met this girl, she was so sweet to me and so friendly I almost had a real crush on her but she kinda did ghosted me after the concert so nothing ever happened between us but I kinda wish for something to happen. Like, I like men, I love looking at men and stuff but sometimes they don’t hit the same and now ive just started watching that kind of stuff again after a really long time. So now im having a second thought, am I really straight as a ruler like ive been saying I am?
