<human>: My best friend has had a lot of guy issues. She liked one for a while, it didn't work out because he was still kind of with his ex, heartbreak, etc., and I was there for her for all of it and helped her through it.

Now, she likes her best guy friend and she always talks about how great of relationship they have. He's still talking to his ex (which she knows), and he's been sleeping with some other people we know (which only I know). 
I told her that if she wants to be with him, she needs to tell him and sort that shit out, and speak now or forever hold your peace. Since she's not his girlfriend, she has no claim to him. She keeps talking about him now, and I don't want to hear about how she's trying to get closer to him; if you don't tell a guy you like him, then you have to shut up.

I don't want to be along for the ride on another emotional roller coaster of hers, but I don't want to be a bad friend. How can I tell her to keep me out of this since I already gave her my two cents?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: best friend likes a guy but won't tell him how she feels, is whining to me about it and it's pissing me off. How do I tell her to shut up without being a crappy friend?
