Who believes in bisexuals?

I honestly want to know. I'm personally gay. And just got dumped by a bi girl. Who doesn't know how "bi" she is. The only people who understand how humiliating that is are my other gay friends. It's happened to them all too. I just kind of need closure. I feel like our relationship meant nothing. And well my gay friends, they don't believe in bi. And I don't know if i do. Personally, I'm not one to tell you who you love. But I really believe that most people say they are bi because they're confused, want attention, or want to make themselves more interesting. Or all of the above. But I'm just curious. And if you're like 12 and saying you're bi... get to know yourself a little better. Please. For the sake of all of us. You think your best friends pretty. Big whoop. Every girl has a crush on her best friend at one point. I don't care how "mature" you are, and honestly the more you little ducklings say that, the more immature I think you are.

So leave a comment, I'll reply asap.
