Maybe I worded it weirdly. l personally wouldn't go out of my way to avoid pretty girls, but I've just come to the realization that must of the time the juice isn't worth the squeeze. Are there pretty girls who have a good head on their shoulders? Absolutely. But 9/10, they can be really guarded and come with more confidence/trust issues than your avg girl.
A legit 8-10 Syrian mate of mine told me something along the lines of "it's hard to discern between the guys who genuinely like me as a person and to pursuit something long term, and those who'll fake a connection just so they can f*ck me." So I completely understand why they can come across as cold/guarded etc.
I'll still approach attractive girls, but I'm x10 more flighty. If I get a whiff that she still needs to work on some deep-seated issues, I'll peace the f*ck out. I've got other priorities and going on a journey of self-exploration with some girl I might not even end up marrying is a waste of my time and hers. Don't know about other guys, but that's been my personal experience
