Here's a clip from Late Night with Jimmy Fallon, featuring Katharine McPhee, an actress and a singer and Russel Brand, an actor and a comedian who's quite open about his promiscuity. I highly recommend watching videos of him flirting with women, he's basically Chad Thundercock, the Slayer of Pussy.

From the very beginning of this clip you can see that Russel wants to fuck Katharine, openly flirting with her. She seems to enjoy his attention, so much that she happily sits on his lap for a brief moment, and lets him hug her and touch her hips in a very intimate way.

Later during the interview, she tells him she's married, after which Russel decides to "fuck off" and leaves the studio. I think her mentioning that was a shit-test, which Russel obviously passed. Maybe they fucked after the show - who knows.

Right before he leaves he yells at her "Be clear!" - he thought she was down to fuck. But clearly she's a loving wife who's just naturally flirty with men and this small chat with Russel doesn't mean anything, right?

This video was taken in 2013. One year later she divorced her husband because of an affair she had with a movie director. Oh my, who would have thought!

Katharine openly flirting with Russel should be a clear message to her husband that he should get a lawyer, he definitely shouldn't ignore her behavior. And same goes for you:

You should never ignore any signs of infidelity from your LTR, wife, or even plate you want to become serious with. Observe how she behaves around other men. Is she flirty? Does she allow other guys to touch her? Does she touch other guys back in a sexual manner? If so, think twice before committing to her. Even if hasn't cheated on you, if she displays that behavior all it takes is her having a convenient excuse ("I drank too much and you weren't there!") and BOOM! You're a cuck.

Also never allow your woman to make your hamster spin by telling you "oh, he's just a friend".

Yeah, a friend that will put his dick inside her soon.
