So I opened up a girl who was quite for a while looking at me in a bar. I thought I will use style's jealous gf opener and this is roughly how the conversation went.
Me - Hey listen. I need an opinion regarding something.
Girl - sure how can I help you.
Me - my friend is dating a girl and he just came out of relationship as well. They went to house together yesterday. The girl while searching through the house found few pictures of his ex girl friend and also some love letters and notes. Before he could explain, she just stormed out of the house and my friend is upset about it. They are not talking anymore. She knew about his ex but still felt bad that he kept the photos while still dating her. So do you think what she did was right? Would you have done the same thing?
Girl - there are people dying and you are worried about such petty issues. You are so stupid.

She said this and just walked away from me. Since I'm a newbie to the game, I had no idea how to follow up or talk to her.

Ps-this happened in germany

I'd say she had some personal issues, but that's just the underlying problem.

Using these types of routines is cringeworthy.

Typical "PUA" mistake.

Dude, you're using a routine to "build attraction" on a girl who's already attracted to you. She was staring at you. Just go say what's up and show her that you like her next time. Don't use a "routine."
