What do I do?!?!👩‍❤️‍👩

Nikki
So I'm currently in sixth form (England) at an all girls school and have been bisexual for about 5 years now, openly for about 3. In September this new girl started and she is absolutely gorgeous😍 at first I thought 'oh yeah she's hot' but now I get butterflies around her, whenever we hug or she's messing around with me (as friends!) I get all giddy and I'm surprised she hasn't noticed. My feelings for her are stronger than any feelings I've had for a boy or girl previous and I don't know what to do. Shit thing is that she is very much into boys and has only a few months ago broke up with her ex of 2 years and they ended on good terms. Since telling one of my friends that I like her that much, she also told me that the girl I like, is a little into girls too. Now my heads all over the place and I don't know what to do! Help pleaseeeee!😩😩
