Scorpio Male Attach how to avoid it?

Hi,
I just met this super fantastic Aquarius girl.
And now my Scorpio friend that has many many girls already try to get her.
I think he is trying to get my girl now. What happend is that he is going via the sister that is ugly like h...

Now how do you expose or avoid a scorpio male attack?
I know they dont have any conscience and very secretive.

Anyone have some suggestions how to expose them?

STOP BEING SO SENSITIVE ABOUT IT AND UNDERSTAND THAT A PERSON IS WHO THEY ARE NOT BECAUSE OF THERE SIGN BUT BECAUSE THEY ARE WHO THEY ARE. IF U WANT THE GIRL ,TELL HIM YOU DO

Well....im a female scorp so how do you know he tried to get her?

I wouldn't be judging the unattractive sister as a bait to get the prettier one,we're not that superficial or good at faking it in this department.Whereas you may only think shes ugly,he could actually like her for other reasons.And your off about the conscience and most people confuse secretive with going about our own business due to not saying much.Talking about everything we're doing is like hearing a record skipping,its all been heard before so why nag about it?Which is what talking about certain,everyday things amount to at least for me anyways is just nagging.The whole:"I gotta go to work"s,"I gotta pick up the kids","I gotta do this",I gotta do that"s,etc.
