Any tips?

Hi there! Im Eli / Kittsumy (both nicknames are great!) , and this is my expirience. 

I recently fall in love with one of my best friends (im bi and she too but the only thing is that she is hard to fall in love and she prefer the boys than girls soo I have it difficult) Were going to name her "Pearl" ok? Well, the thing with pearl is that I was entering a new school and make me friend with her and her best friend (We are going to name her Katie). In that moment I like the best friend of Pearl but we had a situacion and the end is no, so no longer in love with him. And since the last tuesday or sunday (don't remember really) I started being confuse with her, like I was falling in love with her. And I think is a yes, like yes I love her and no more like a friend. It all started in a sleepover in the house of Katie, Pearl and I we're so together that time (in general allways but especially that time make me fell consufe) I will not enter in big details but since that time I haven't been the same girl with her friends. Like I really love her very bad. Obviously I wasn't going to confess to her, I will never do it to don't end the friendship, and if I do it will be in some years, maybe give me time to think good or idk. But the think is that Katie told me that It wasn't good idea to fall in love with Pearl cause she like her best friend knows more than I. The problems is are 1. She NEVER had fall in love before with a girl 2. Is very DIFFICULT to make her fall in love 3. As I said before she tend to fall in love with only boys (but she is still a bisexual) I really need help cause that make me so sad and I know if the thing I want doesn't happend I would probably kill myself (just "joking") But I was thinking, should I delete my feelings at all? What if just maybe I make her to fall in love with me? 

Its been so long since I want to public this soo there have been another intereactions with Pearl ( a little romantic I think) but anyways, any recommendations?
