if u have a best friend wo tends to get along with every one and is a beautifull but doesn't usually mean to but sometin=mes well flirt w/ your boyfriend and everyone does it here and there unconditional not even relizing it but she so skinny and perrty not hard to wounder should u be worried?

If you are asking should you be worried about your pretty girlfriend flirting with your best friend, maybe you should.

If you are asking if its normal for a pretty girl to flirt with guys, yes it is.

If you are asking if your best girlfriend should be flirting with your boyfriend, I'd have to wonder if your best friend should be your best friend if she's OK with flirting with your boyfriend!

Can you explain a little bit more? Try giving a little bit of background and explaining it a tad better...
