Before I know all these seduction stuff, my way of starting a LTR is like:

"I'm in love with you. I'm dying for you. You're the one. Bla bla bla..."

And then we'd likely be a couple. It even worked when my SMV was way below the average.

After reading many PUA stuff, now my approach to dating sounds like this:

"Aight I'm shopping for a girl. You seem OK. Wanna come over and suck my dick?"

And it doesn't work for other than nightclub trash.

What I'm doing wrong?

Is there a way to formulate that falling in love game for LTR?
