Don't Ask My Opinion. Please?

Ok, imagine a girl called (for the sake of this post) Penelope. She likes this guy name, Pepe. Pepe is a musclebound, nice guy, but somewhat shady character when it comes to women. His ex-girlfriend, Perfume, has been texting and messaging Penelope nonstop trashing her, and saying how Pepe still goes for the gold between her legs. Penelope asks me for advice, but quite honestly, I don't want her to be with Pepe, cause he's a shady guy when it comes to girls. Penelope is a sweet, innocent girl. But what do I say? I tell Penelope to go with her gut (which she says is a bad guy) and ask herself if all this drama is worth it. Does Penelope take my advice? Basically no. Then why did she even ask me? Stuff like that pisses me off. I don't care what Penelope does now. If Penelope wants to be with a guy that will eventually cheat on her, then i'll let Penelope go ahead. Why are the pretty ones the ones that make the worst decisions?
