First words, last news

so it ended up like this, im really confuse right now, cause everything i thought had become to a really big mindgame,let me explain, or at least try, to explain:
Right now my  best friend Dess, turns out to be my new crush and i dont even know how that happend, cause a week ago i was really in love with her best friend Mel, she was my crush and its hard to say things were going to work between us, but its a battle i been there for at least 2 years, two fucking years!!! and now when theres a light to be with her, my heart take this new posture about who really care about, and its all killing me right now, cause she is dating my boss who also its my teacher Richard, and my male best friend Bob thinks that i should let the things happened naturally but i screwed everything up when i began flirting with her niece Joyce,
i don't know what imma gonna do....
