How close is too close?

So i have this friend, he's my best friend actually. we've been best friends for over six months now. He knows everything there could possibly be about me and vise versa. He loves me an is in love with me. i love him as well, but my question is, how close is too close? could he actually be the one for me? could he be the one for me in the end? I dont know. Thing is, with eveyday that goes by, hanging out with him, only keeps me wondering at the end of the night. He's been there for me when i was with my ex boyfriend for 4 1/2 months (Dec-Apr). throught the break ups and the get back togethers, my best friend has been there for me. he hasn't been with anyone because he's been waiting to be with me all this time. & i am fully awear of this. Its sweet. &i've been going on with my life, talking to other guys and what not. and so has he. thing is, im soo jealous whenever i fid out that he's talking to another girl or if he tells me that he's gonna be hooking up with one. Ill usually tell him that i dont want him too, and he'll most likely wont after that. But for someone who has gone through this before, can you help? i want to know what the reason is that he's my best friend, but he's too close to me as if was meant to be more..

Love songs

Practically everyone listens to music, and time and time again, there will be songs on the radio or an iPod that remind you of something or someone. My Question is, why do people dedicate songs to a special someone or a special occasion? If things were to go down hill with anything, those songs that we dedicated will only hurt us in the end. I've done it before, i can't even tell you how many songs i've dedicated to friends and family, and to even boys i've had strong feelings for. So why do we do it? Is it because we have trouble finding those perfect, "exactly how i feel" lyrics in the songs? No one knows, but in the end it only hurts. Sure it may make things better eventually but people dont understand that when you dedicate a song to something or someone, it means they care, that they're putting their emotions into whatever it is their dedicating the song to. I hope im not the only one that is actually understanding this. Who knows why we do it, but all i know is that, even though dedicating song will hurt in the end, i know that im going to continue doing it. but thats just me.
