So, I was talking to someone (A guy) and we were talking about shit tests, He is a Dating coach. I was just talking to him online.

I've read the Illimitable Men's guide to shit tests.

So he asked me, "If a chick says "Do you have a girlfriend?" What do you say?

I said, "I can simply lie and say "Yes, I have a girlfriend(blah blah)" even if I don't have a girlfriend".

To which he said this: "Yes, you can lie, but then you have to deal with the negative consequences of that lie. And why would you lie about having a girlfriend anyway? Aren't you trying to seduce her? Most women don't want to play second fiddle or help a guy cheat, so by saying you have a girlfriend you're just making your chances worse. Plus you'll look like a complete and idiotic asshole if she finds out you lied, which is typically just a matter of time. You will also likely have hurt her feelings and now given her potentially lasting trust issues that may stay with her long after you stopped interacting with her. And then she might go tell every woman she knows that you're a liar. If you get a girlfriend at some point, this woman might reach out to your girlfriend on social media and tell her how you're a lying manipulating asshole. So yeah, you can lie. If you're okay with all the potential backlash and worse chance of succeeding."

This guy is very popular in the dating scene but isn't his take opposite to that of RP? Isn't "Do you have a girlfriend?" translates to "Are you pre-selected"?. So how come it will lower my chance of succeeding?

Thanks.
