Serious answer then is STOP GIVING A FUCK. You want a girlfriend.. treat women like a housecat. (Disclaimer this is for a girlfriend not getting laid)
If meet a new strange cat and you immediately lay into it, run at the cat, try to touch it, talk to it, chase it, be loud? That cat will be under a couch or on top of a bookcase wanting nothing to do with you. Women and cats sense the same energy and flee.
Instead stop giving a fuck. Like with a cat, be in the proximity of women but do other shit. Ignore them or barely acknowledge them. Be polite and funny but be there to do other stuff. Dont do any of that pickup culture neg shit just go hang out at a party or event and have a good time. The goal is not to meet women but just have fun near them. Cats and women will be intrigued, they will come investigate and then get your attention. Then meet their attention level with yours. Dont try to grab them suddenly or admit you like them. Polite conversation meet polite conversation. Match their energy. Increase the attention slowly.
