My friend said she's in love with my boyfriend. What the hell is she on?

Okay so I was being a lurking girlfriend and went in my boyfriends phone. Who can blame me? He's been acting super distant lately and I don't feel like he's into me as much as I'm into him. I posted on his Facebook wall " can't wait to change my last name to yours" and he didn't even reply or "like" it
I'm fed up.
Turns out my boyfriend has been facebook messaging my friend all day everyday for over a week.
This is how the messages went :
" we can't type like this forever sheesh I can't ask for your number so help a dude out
Then my friend goes " what you talking bout "
And he was like " you wanna Skype"'

Then in another conversation I read between them it went like
My boyfriend : you need to leave Bob and get with a real deal john. He's human
My friend : but Bob can't break my heart
My boyfriend : but he can't fully satisfy you either. He can't hold you or surprise you .. Lemme stop "
I couldn't even read the rest without tearing up crying
My friend said she's falling for him but she didn't mean to. She initially wanted them to be just friends. How do you fall in love with someone in just a week of talking ? That's bull. Sound like some middle school crap
