Hey guys, how you doing?

I wonder if I can use some dhv routine in comfort phase to cause jealousy (I didn't KC yet, but already started rapport)

I tried smth like this:

Is it wrong to dump a girl with a phone message?
She: I didn't know you had a gf. Very curious, huh?

It's nothing serious, something that occurred 3 mths ago. Her boyfriend texted me asking if I had banged her gf. I didn't even know this guy.
She: you are smart enough to solve this alone.
Me: it's obvious that I wanna cut this off.. Bla Bla

Then she got extremely nervous / jealous. Am I doing this right? How can I continue this game? Rapport again?

Thanks
